Same issue on our side. Team V96BHRSU6X, bundle com.moneytrain (App ID enabled for Sign in with Apple for several weeks, capability verified via App Store Connect API). Filed FB24518599. On device (iPhone, iOS 26.6): the authorization sheet completes, then iOS shows "Sign Up Not Completed" and no credential is returned. Device logs show: akd(AppleIDAuthSupport): "M2 missing (bad password)" SRP authentication with server failed, AKAuthenticationServerError Code=-24000 serverProvidedData is nil, AUTH_ALERT_SIGN_UP_NOT_COMPLETED Independent check: https://appleid.apple.com/auth/authorize?client_id=com.moneytrain still returns {"errorCode":"invalid_client"} as of day 5. This exactly matches the AKSQLError -6003 "No applications were found with the provided Client ID" signature in this thread. Could the server-side Sign in with Apple registration for this App ID/team please be re-provisioned? Thank you.
