[Bug] in_app_purchase event not reported for iOS when using Unity IAP 5.0.0-pre.8 package

[JottoWorol]

Description

After switching to the new In App Purchasing package, in_app_purchase event stopped being automatically sent for iOS. I suspect it's because of StoreKit2 usage introduction in latter versions

Overall integration seems ok as manual events & crashlytics are being sent successfully.

Reproducing the issue

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @JottoWorol, thanks for reaching out. I believe IAP events rely on an integration with Analytics and Apple App Store, using StoreKit. And if you're using StoreKit 2, it's possible some code changes may be preventing your IAP events from being logged as expected. I would suggest double-checking if you've setup the required code properly.

It looks like this issue seems to lean towards your data and implementation, rather than the SDK. And I think the best course of action here would be to reach out to Firebase support as they have better visibility and tooling to investigate issues on your project and data.

With that, there doesn't seem to be anything else we can do on the SDK side, so I'll go ahead and close this thread for now. If you have info that shows that the SDK is the issue, feel free to let me know, and we can reopen this thread.
