Sign in with Apple Not Working – "Sign Up Not Completed" Error

We have integrated Sign in with Apple into our iOS project using the recommended implementation from your documentation,However, we are experiencing issues when testing with the following: Bundle ID: com.app.xxx Using real certificates from our Apple Developer account

Issue Details: On real devices, after entering the Apple ID password, we receive a message saying: "Sign-up not completed" On simulators, the flow gets stuck after entering the password no further progress occurs. We are not receiving any explicit error messages in the console or logs. We also tested with the official Apple sign-in demo code from the documentation link above, and the same issue occurred. Our team has confirmed that all necessary configurations have been set correctly, and the same implementation works on other accounts.

We would appreciate your assistance in identifying the root cause and helping us resolve this issue.

Thank you,
