Adding another affected team with the same web-flow signature. Team ID: PPQ8HG3N23 Primary App ID: com.hikond.atune Services ID: com.hikond.atune.web From atune.hikond.com, Apple’s authorization sheet appears and Touch ID completes, then “Sign Up Not Completed”. Supabase logs the /authorize 302 redirect to Apple, but Apple never POSTs to the registered callback, so no credential or session reaches the backend. Verified: the Services ID is linked to the primary App ID; the exact domain and return URL are saved; both client IDs are configured with the web Services ID first; and Apple client authentication is accepted. Native Sign in with Apple for the same account already works. Filed as FB24551300. Could Apple please apply the same server-side Sign in with Apple registration repair/re-provisioning that resolved other affected teams in this thread? Thank you.
