we’ll investigate this further tomorrow (monday). this impacts other tools as well, see this fastlane issue, for example.
if you have successfully run a build before, you don’t need to communicate with apple at all to run another build. we just do this to validate the credentials in case they are expired.
if you are using expo build: expo build:ios --skip-credentials-check
if you are using eas build: eas build -p ios --non-interactive
