Everything seems to work fine when I upload my app using Xcode 13.0, but very soon after the upload successfully completes I get this email from Apple: Dear Developer, We identified one or more issues with a recent delivery for your app, "MyApp" 1.0.0 (2021.10.24.1). Please correct the following issues, then upload again. Best regards, The App Store Team The email names no issues, and the builds page for my app at appstoreconnect.apple.com doesn't show my upload at all, not even as failed. The last time I uploaded a build was about a month ago, and it worked fine. I suspect Xcode was auto-updated to 13.0 since my last upload and that's the source of the problem, but I have no clues to go on. How can I figure out what's going wrong?
