Appstore rejects app because of error when signing in with Firebase authentication, but it works fine for me.

I have tried to get my flutter app aproved for appstore. My app uses Firebase as a backend and Firebase authentication to sign in

The app works perfectly for me to sign in and using the database on diffrent iOS emulators and physical devices through testflight. But now two times in a row my app have been rejected beacuse of: "we discovered one or more bugs in your app. Specifically, your app loaded indefinitely upon login". They specify:

  • Device type: iPad - OS version: iOS 16.4.

But I cant replicate this error neither in the emulator or in my physical Ipad iOS version 16.4 and it works fine for me.

I dont know if the error occurs in Iphone for them also, or if they just started with Ipad and then aborted when that didnt work.

I read that there have been some problems with Firebase and iOS, could this be the problem, that something's wrong between google and apple?

The error defenitly has to do with Firebase Authentication since its where the error with the indefinitely loading spinner occurs.

Could it maybe have to do with something that Apples tester is located in another country than me (Sweden) and thats why it wont work, that Firebase is limited to some regions?

I havent got the latest flutter package of firebase_auth in my app, could that be it? I have package 4.1.1 which was uploaded 5 months ago.

Do anyone have any suggestions? Im not sure what to do.

I'm having a similar report from Apple. App crash on Sign in with apple
