The new version of my application was rejected due to "app loading indefinitely after Sign in with Apple". They tested it on iOS 14.6, iPhone and iPad.
I didn't change anything about this part on the new version, and it works fine on Android and web site.
My config is React Native and the package invertase/react-native-apple-authentication.
Here are the tests I did and the informations I gathered:
Some people say Apple sign in doesn't work at all on simulator, but others say it works on simulator with iOS 13.
So I tested it on a simulator with iOS 14: it loads indefinitely.
Then I tested it on a simulator with iOS 13: it loads then nothing happens (it stays on my authentification screen).
Then I tested it on a real device, iPhone SE with iOS 14, and it's another problem: when I click on the button, it always show the pop-up for going into the settings and logging, even if I'm already logged. I have to connect to iCloud for Apple sign in to work, which I don't think was a thing before.
Are there known new issues with Apple sign in?
