To add some background, my app is also macCatalyst, seems we have another report in this thread.

I've opened an FB and a TSI, here's my number: FB10196751.

It's a pure Apple server-side validation error, I don't think we should do anything except wait, unfortunately it's been several days and Apple haven't responded.

I literally filed a TSI and heard back nothing from them, it's been several days.

Thanks for sharing, that's really good news, I have been refreshing the forums for days.
