Sign in with Apple returns "configuration not found" - all settings correct

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.

Thanks for the post, it seems like that issue has already reported about firebase?

Can you take a look at this thread? https://developer.apple.com/forums/thread/826547

Let me know if that’s the same issue you are getting as well as I think that reporting that to Firebase may help other developers.
