I've also created a couple of support tickets and no answers so far. I've tried multiple things like that as well. Adding a new build, new version number, metadata... I also even tried doing it trough their API and no luck. I wonder what else we can try?

Thanks for answering @begiljen! Yesterday I called Apple from the Contact page and I talked to a representative and opened a case about this issue. I sent them a video showing the issue and how even if I cancel the submission when I submitted again it always go into the Ready For Review state. I'll let you know as well if I hear anything back from them.

No solution neither for me. :-( I've created a support ticket and they said that they would give an answer in 24/48 hours about the matter but it's been almost a week and I haven't heard anything from back from support.

I've contacted support again and they've said that the Engineering team is looking at it but that's all they said. No time-frame for a fix, possible solution or work-around. 😢

Same for me. I got an email from Apple Support that the issue was fixed. I cancel my submission and I re-submit it again and now the state changed into "Waiting for Review" as expected. Thank you App Store Connect folks for fixing this 🙌
