Sign Up Not Completed" for every new App ID on our team; older App ID works — FB23726069

Native Sign in with Apple fails with "Sign Up Not Completed" inside the AuthenticationServices sheet for every NEWLY registered App ID on our team (V4DCPCSM54) — including a clean-room probe App ID created via the ASC API with the capability enabled at creation — while an App ID registered in 2025 on the same team works. Entitlements, profiles, and capability config are all verified correct; capability toggle and fresh builds change nothing. This matches the server-side registration issue described in thread 790827.

Filed as FB[23726069] with full details. Would appreciate DTS taking a look — this is currently blocking our App Store review (rejected 2.1(a)).

Our case supports your registration-date finding from the other direction: our entire team is new (enrolled 2026-07-13, capability first enabled 2026-07-16), so we have no pre-2026 App ID to fall back on — and every App ID of the team fails identically with "Sign Up Not Completed" / ASAuthorizationError 1001, including a clean-room probe App ID created specifically to test this. If the failure is scoped to recently-registered App IDs not propagating into the identity service, a brand-new team fails everywhere, which is exactly what we see.

Ruled out: entitlement (verified in the embedded provisioning profile), agreements (Active), scopes (unset and .fullName), signing (Xcode and TestFlight both fail), device/Apple ID (3 devices, 2 independent Apple IDs; third-party SIWA sign-ups work fine for the same Apple IDs). akd log with the Accounts profile shows the GSA sign-up SRP returning 200 with M2 missing (bad password) and null account fields — the identity server aborting the sign-up ceremony server-side.

Filed as FB23826495, referencing yours (FB23726069) and FB23716661. Precedents suggest Apple fixes this class server-side: thread 790827 (official, June 2025, 5 days) and thread 790323 (same M2 signature, 11 days).

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.
