I am unable to proceed with TestFlight in App Store Connect. The operation returns HTTP 422 with code ENTITY_UNPROCESSABLE.BETA_CONTRACT_MISSING, detail "Beta Contract is missing", and title "Beta Contract is missing for the app."
I have already opened a support case about this issue, but have not received a response, and the problem is still occurring.
What does this error mean, where can I check or accept the required beta agreement, and what steps can resolve it if the agreement is not available in App Store Connect?
