We are experiencing the same issue on Apple Developer Team A9FLT346MM. For both com.shamrocksgames.thuru304 and com.shamrocksgames.turup29, the native Sign in with Apple sheet opens correctly, Share My Email is selected, Face ID completes successfully, and Apple then displays “Sign-Up Not Completed” without returning a credential. Both App IDs are explicit primary App IDs with Sign in with Apple enabled. The signed entitlements and embedded provisioning profiles have also been verified. No authentication request reaches our backend. Feedback submitted: FB23876773
