In my case, I had added the wrong bundle ID/ iOS application to Firebase. So I went back to the project on Firebase, clicked Settings icon, clicked Project Settings, and removed the iOS app, and re-added the correct application.

This could potentially fix problems on Android too, ensure the package name is correct.
