The UI only says "There was an error processing your request". The network response is:
POST /iris/v1/betaAppReviewSubmissions → 422 ENTITY_UNPROCESSABLE.BETA_CONTRACT_MISSING
In Business → Agreements, all agreements are active and there is nothing left to accept. The build is processed and valid. Re-uploading, bumping the version and creating a new app version change nothing, so it looks like the account's beta contract flag didn't update after renewal. We contacted Developer Support over a week ago (Distribution → TestFlight) and haven't heard back. Could someone from Apple check the account's beta contract status or pass this to the App Store Connect team? Error ID: c9e61135-7a2f-4f52-bc39-bd3437d94440
