In regards to this issue, I was able to upload and successfully processed it (using Unity 2021.3.4f1 and XCode 13.4.1), so I can say it was resolved for us.

Yep, I'm using Unity 2021 and Xcode 13.4.1 and having the same issue.

I'm experiencing the same issue. I can't upload the app ...

That's good advice. Focus on the product and how to deliver the best possible experience to your users and they will be happy to use your app, despite some faked reviews.
