👀 We've just linked this issue to our internal tracker and notified the team. Thank you for reporting, we're checking this out!

HaleyRevcat · 2023-05-23T17:34:16Z

Hi, this is happening from Apple's end. This is most likely from a iOS sandbox user with a lot of receipts so it is causing a delay. I recommend you try making a new sandbox user, this should remove the delay.

JustinWeru12 · 2023-05-23T18:17:20Z

Hello, this is happening in production. We are not using sandbox users.

NachoSoto · 2023-05-23T18:23:19Z

Could you share debug logs when you reproduce the issue?

iOS app is taking ~8 seconds to load the iOS payment page

Could you describe what exactly takes 8 seconds? Is it the time from the user entering AppStore credentials or accepting the purchase until the time your flutter app receives the confirmation? Or the time between accepting the purchase and receiving the "purchase success" alert from iOS?

babirms · 2023-05-23T19:20:41Z

Hello, I'm having the exact same problem.

When I click the button to make the purchase, in Android works perfectly, in iOs it takes ~4 to 5 seconds to show the Apple payment modal. It doesn't show any error on the console.

Lib version: 4.12.0

NachoSoto · 2023-05-23T19:29:14Z

It would be helpful if you could attached debug logs as well as the code you're using to call purchase. Thanks!

babirms · 2023-05-23T19:45:43Z

I used await Purchases.purchasePackage(plan); to call when I click the button and then, it showed the following logs:

[Purchases] - DEBUG: ℹ️ Vending Offerings from cache
[Purchases] - INFO: 💰 Purchasing Product 'product' from package in Offering 'default_offering'

babirms · 2023-05-26T14:23:52Z

@NachoSoto hey! Do you have any updates on this? I'm still having this problem (same log as before)

NachoSoto · 2023-05-26T14:25:51Z

My guess is the delay happens between the "adding payment" and "updated transaction" logs. Can you confirm that?

armandojimenez · 2023-06-05T16:22:20Z

Is there any update on this? seeing this in dev

unilogica · 2023-06-08T11:14:19Z

The delay on iOS is really too long. As a palliative solution, I block the UI with a loader and call the purchasePackage only after UI is already blocked, but there will be a loader layer on top of another loader in the bottom sheet, a weird experience, because I can't dismiss the first loader from the layer down and keep visible due to opacity from de second layer.

I also tested if it was possible to get the in app purchase screen from the hierarchy of components above, using an observable notification, but as it is native code it is not a simple task to detect when it is launched on the screen, and there isn't another method that triggers any action at the exact moment the native bottom sheet payment is shown.

dimakrest · 2023-06-17T04:26:23Z

It happens for me for both production and new sandbox user. After calling the purchasePackage function it takes ~ 7 seconds until iOS payment page loads.
Tested it both with 5.0.0 and 4.13.0

Since it takes a lot of time to load and complete the purchase the abandonment rate is very high and people do not complete payment!!
if there's no solution I would have to switch to other company

NachoSoto · 2023-06-20T20:44:40Z

I just tested this and the delay is less than 1 second both on simulator (iOS 16.4) and on device (iOS 17.0 beta 1).
Also tested on the iOS 14.4 simulator with no issues.

When you reproduce this, could you pause the debugger on Xcode and send us a trace of what all the threads look like?

NachoSoto · 2023-06-20T22:50:36Z

I just randomly saw this from a completely different app (not even Flutter).

I confirmed that the delay happens after we call SKPaymentQueue.add(payment), and none of the threads are locked or anything. Meaning the delay is entirely on Apple's side.

Also confirmed this happens even without our SDK, same delay on both StoreKit 1 and StoreKit 2.

I just filed FB12402539 to Apple including my device diagnostics. I recommend you do the same to maximize the chances of Apple fixing this.

dimakrest · 2023-07-01T09:55:11Z

@NachoSoto Thanks for the update

fatherOfLegends · 2023-07-20T21:41:27Z

@NachoSoto this is not a random delay, it is a consistent delay. We just updated from flutter_purchases: 4.11.1 to 5.3.0. The older version was not slow, the new version is slow. We are forced to upgrade soon but my company is concerned about this delay causing churn.

pratikbaid3 · 2023-07-20T22:57:27Z

@NachoSoto I am facing the same issue. The await for purchase package never completes

NachoSoto · 2023-07-20T23:03:47Z

I’d appreciate it if you could provide any additional details to help us debug this 🙏

NachoSoto · 2023-07-21T06:01:27Z

Can you send us the complete logs, including from SDK initialization?
Also, any chance you have any other StoreKit SDK in your app? (Example: RevenueCat/purchases-ios#2415 (comment))

pratikbaid3 · 2023-07-21T06:03:13Z

  static configureSDK() async {
    if (Platform.isIOS || Platform.isMacOS) {
      StoreConfig(
        store: Store.appStore,
        apiKey: Constants.appleApiKey,
      );
    }
    await Purchases.setLogLevel(LogLevel.debug);

    PurchasesConfiguration configuration;
    if (StoreConfig.isForAmazonAppstore()) {
      configuration = AmazonConfiguration(StoreConfig.instance.apiKey)
        ..appUserID = null
        ..observerMode = false;
    } else {
      configuration = PurchasesConfiguration(StoreConfig.instance.apiKey)
        ..appUserID = null
        ..observerMode = false;
    }
    await Purchases.configure(configuration);
  }

pratikbaid3 · 2023-07-21T06:05:36Z

I also have in_app_purchase

NachoSoto · 2023-07-21T06:12:24Z

Do you mind filing a separate issue for that so we can keep this about slow StoreKit calls?

pratikbaid3 · 2023-07-21T06:13:50Z

Sure @NachoSoto. I dont think it is slow, it never seems to be complete. I waited for 25 mins.

NachoSoto · 2023-07-21T06:14:25Z

Yup, seems like a separare issue.

pratikbaid3 · 2023-07-21T06:22:15Z

@NachoSoto I think this might be related since the issues discussed in the thread here is exactly what we are facing

Lyesbcb · 2023-08-09T14:49:51Z

Hello, I have the same issue only on IOS.

I use React native SDK.

The paiement popup are opening in less than 1 second on android but on IOS it's take 8 seconds !

I want to release my app but I can't do it with this delay.

Do you have idea ?

NachoSoto · 2023-08-09T14:55:07Z

This is a known iOS issue, especially on sandbox.
We've filed a bug with Apple but have not heard back yet: FB12402539

I recommend filing more feedbacks directly with Apple. The more duplicate they get, the higher the chances they'll address it.

I just sent the version on Testflight and the delay is always so long!

I'm going to send to production like this, hope I don't lose too many customers :/

djsjr · 2023-09-11T20:16:47Z

Are there ANY flutter users for which this bug ONLY occurs in TestFlight (sandbox users) and not in production apps?

This issue is exactly like this one for the in_app_purchases plugin, except that OP claims it works fine in production.

I am releasing at app in a few weeks and can not have this long a wait for purchases! Any headway or more info on this? @HaleyRevcat @NachoSoto

nguyen703 · 2023-12-07T15:01:10Z

Are there any updates on this issue? I encountered the same on iOS 17, iPhone XS Max :(

TurkiTAK · 2024-02-03T21:08:54Z

I sent an update to my users and now stuck with this nonsense.
It's not even a delay it's just purely not working.

How the hell can this happen

YonatanLeulseged · 2024-02-07T16:19:00Z

I am having an issue where it gets to the Purchases.purchasePackage method and the app reaches out to Apple's end and never gets a response back. Passing in aPackage parameter that I've console logged and it has a package being sent. Getting this error:

tcp_input [C1.1.1.1:3] flags=4 seq=3,963,150,005, ack=0, win=0 state=8 rcv_nxt=3,963,150,005, snd_una=3,069,187,791

Has anyone ever gotten this before?

atakangl · 2024-09-20T13:58:04Z

I am facing the same issue.

Happens only on Apple iPhone.
I use flutter.
There is no issue seen. And not too long, method just does not respond.

I have transferred my app to another App Store developer account, and have transferred my app to another Revenuecat account. Issue started to happen in same day. No update released and no other changes in the day.

I have taken all required actions for transferring app. Webhook works fine. Users can purchase, webhook send to data to my server. But the method does not respond in client side.

minhdanh · 2024-10-08T09:21:26Z

I added code to track the purchase time on production, and for iOS many purchases seem to take very long.
This is the code I used when a user starts purchasing a subscription:

                              final startPurchaseTime = DateTime.now();
                              setState(() {
                                isLoading = true;
                              });
                              try {
                                final CustomerInfo customerInfo = await Purchases.purchasePackage(packages![selectedPackageIndex!]);
                                final now = DateTime.now();
                                final parameters = {
                                  "status": "success",
                                  "user_id": user!.isFirebaseUser ? user.id : customerInfo.originalAppUserId,
                                  "package": packages![selectedPackageIndex!].storeProduct.identifier,
                                  "platform": Platform.operatingSystem,
                                  "time": now.difference(startPurchaseTime).inMilliseconds,
                                };
                               logAnalyticsEvent("user_purchased_subscription", parameters);
                              } on PlatformException catch (e, stackTrace) {
                                final errorCode = PurchasesErrorHelper.getErrorCode(e);
                                final customerInfo = await Purchases.getCustomerInfo();
                                final now = DateTime.now();
                                final parameters = {
                                  "status": "failed",
                                  "user_id": user!.isFirebaseUser ? user.id : customerInfo.originalAppUserId,
                                  "error_code": errorCode.toString(),
                                  "error_name": errorCode.name,
                                  "package": packages![selectedPackageIndex!].storeProduct.identifier,
                                  "platform": Platform.operatingSystem,
                                  "time": now.difference(startPurchaseTime).inMilliseconds,
                                };
                               logAnalyticsEvent("user_purchased_subscription", parameters);
                              }
                              setState(() {
                                isLoading = false;
                              });

Here you can see it took almost 51.4 seconds until the purchased is cancelled. I guess the user did not want to wait for more:

It should be noted that not all purchases take this long. Some finished in 13 seconds.
On Android it takes about 10 seconds, never seen a purchase took more than 50 seconds.

What can we do about this?
