I've been struggling with "Sign in with Apple" for days. Firebase Authentication returns "configuration not found". I've tried everything.
My configuration (all verified correct):
- App ID: com.pome.ai
- Services ID: come.pome.ai
- Key ID: 8UXM48JT9D (newly created)
- Apple Team ID: KDAMDMPNAW
- Domain: pome-ai.firebaseapp.com
- Return URL: https://pome-ai.firebaseapp.com/__/auth/handler
What works:
- Android version (Google Sign-In) works perfectly
- Anonymous sign-in works
What I tried:
- Created new Service ID and Key multiple times
- Verified Return URL has double underscore (__)
- Added authorized domains in Firebase
- Cleared iPhone cache, reinstalled app, restarted device
- Tested on different networks
The error occurs only on iOS when tapping "Sign in with Apple". Firebase returns "configuration not found". Any help would be greatly appreciated.
