Same failure signature here. Adding our team to the list. Team ID: S9S87W59A8 Bundle ID: com.agora.fr App ID resource: TP9N3B3CWR Symptom: the native ASAuthorizationAppleIDProvider sheet renders, names the app, offers name and email, then shows "Sign Up Not Completed". The delegate returns ASAuthorizationError.canceled with an empty userInfo and no NSUnderlyingError, so nothing diagnosable reaches the app. Device logs show AKAuthenticationServerError -24000 "Invalid client." with HTTP status 200. Native only. No Services ID, no web flow, no grouping. Explicit primary App ID. APPLE_ID_AUTH is enabled with APPLE_ID_AUTH_APP_CONSENT / PRIMARY_APP_CONSENT, enabled on 2026-08-29, which puts us in the same window as the other reports here. Failure appeared immediately and has been continuous since. Verified on our side, all of it measured rather than assumed: com.apple.developer.applesignin = ["Default"] present in the signed binary and in the embedded provisioning profile (S9S87W59A8.com.agora.fr) capability read back through the App Store Connect API, settings intact developer agreements: there was one pending, it has been accepted, no change capability removed and re-added through the App Store Connect API, with the provisioning profile regenerated afterwards (xcodebuild -allowProvisioningUpdates), no change eas credentials capability sync reports "Synced capabilities: No updates", a third independent confirmation that the configuration matches Apple's records tested with and without a nonce, and with both shared and hidden email, all identical Apple system status shows no incident on Sign in with Apple, Apple Account or Certificates, Identifiers & Profiles Data point that may help narrow it: Sign in with Apple completes normally in OTHER apps on the same device with the same Apple ID. Only this App ID fails, which matches the client ID lookup failure described earlier in this thread. Could Apple please apply the same server-side Sign in with Apple registration repair that resolved GW7XA5CX69 and FRL3DTJQ62 to Team ID S9S87W59A8?
