Hi – We're having this exact issue with this same capability (default mail app) after approval. It's been approved for App Store and Dev, but not Ad-Hoc, so it's blocking distribution on Xcode Cloud. I've written in with a report that also links to this thread, but have not heard back yet. Are you able to take a look? Our bundle id is so.notion.Mail. We really appreciate it.
