I have a new "independent" watchOS 8 app that I wish to put in the App Store. I archive it and try to push the archive via Xcode Organizer/Distribute. It passes all the tests and uploads roughly the correct about of data (size of .ipa) to a blobstore.apple.com URL. Then it just stops, for up to hours before I kill the process.
Is there a log file somewhere which monitors the app upload process so I can try to diagnose the issue? I ran through a number on logs in Console but did not see anything related. Any suggestions?
