I have been facing the same issue for the past 3 hours, tried many things suggested all over. Finally the approach in This Link worked for me and now I've uploaded the build to App Store. Also adding the workaround here just in case if you don't want to check the above link, Here's a workaround: Organizer -> Distribute App -> App Store Connect -> Export -> NOW DISABLE WIFI / INTERNET (else will fail) -> Exported .ipa Now use Transporter App -> Login to same account -> Add .ipa -> Upload works ! Transporter can be downloaded here: Transporter App
