Notifications sometimes don't work on android app in release mode, changed upon installation.

[Pazamozaurus]

I'm using react-native-push-notifications in my android app(android 10, Samsung galaxy s10).

I have a very weird problem, and that is sometimes I don't get any notifications in my released app (in the debug version it works great).
But the point is, it's not that sometimes I get the notifications and sometimes don't, but rather it depends on when I install my app.
It can be that after I install my app I won't get notifications at all, but after I delete it and re-install, it suddenly can get notifications again.

I really can't figure out what's going on and why deleting and re-installing the app suddenly makes it accept notifications (re-installation doesn't 100% help it to start get notifications, sometimes I need to install and re-install it a couple of times before I can get it.

My version of react native is 0.61.4 and version 3.1.9 of react-native-push-notification.

I'm not sure what kind of another info/configuration about my app I should point out, because I really have no clue what can cause such a phenomenon.
Just to clarify, all the other notifications in my phone work properly without any problems.

Other clarifications: I'm talking about remote notifications of course that I send through firebase

After some debugging I found out that indeed when the notifications don't work and I try to send a message to the token I receive on the onRegister function, I get a "NotRegistered" error from FCM.

But I really have no clue why the registration sometimes work and sometimes doesn't...

Hi @Pazamozaurus,
Can you check if PR #1355 resolve your issue ?
Thanks

Hi @Dallas62
Eventually what solved my issue was that in my android/build.gradle file I had the following configuration

googlePlayServicesVersion = "+"
firebaseVersion = "+"
(As it appears in the usages example here).
In this configuration the notifications worked perfectly in debug mode and sometimes on release mode.

When I changed it to specific versions, like
googlePlayServicesVersion = "16.1.0"
firebaseVersion = "17.3.4"

It worked correctly on both debug and release mode. I'm not even sure if these are the correct versions of googlePlayServices and firebaseVersion I use, but at least for me it worked.

Thanks for this feedback!
Since I may take some times to reproduce this issue, it would be great if you test a small change to your project.
Change the current version of react-native-push-notification:

    "react-native-push-notification": "git+https://github.com/jackw-kounta/react-native-push-notification.git"

then run:

yarn install

OR

npm install

This will allow you to test the PR.
Then if the PR fix this issue, I will be able to validate the PR to release it ;)
You will have to revert your following changes before test :

googlePlayServicesVersion = "16.1.0"
firebaseVersion = "17.3.4"

Thanks a lot!

I am also facing a similar issue, using version react-native-push-notification : ^3.1.9
do you suggest updating the package will solve the issue or should I try the above suggestion of changing the googlePlayServicesVersion and firebaseVersion ?
