Xcode 12.3 simulator running 14.2, same issue.

I got this error message just over 12 hours ago. I ran the diagnostic command in TN2318 shell codesign --verify -vvvv -R='anchor apple generic and certificate 1[field.1.2.840.113635.100.6.2.1] exists and (certificate leaf[field.1.2.840.113635.100.6.1.2] exists or certificate leaf[field.1.2.840.113635.100.6.1.4] exists)' /path/to/the.app and got the normal result /Users/no/Library/Developer/Xcode/Archives/2021-03-11/Twinkle 3-11-21, 11.49 PM.xcarchive/Products/Applications/Twinkle.app: valid on disk /Users/no/Library/Developer/Xcode/Archives/2021-03-11/Twinkle 3-11-21, 11.49 PM.xcarchive/Products/Applications/Twinkle.app: satisfies its Designated Requirement /Users/no/Library/Developer/Xcode/Archives/2021-03-11/Twinkle 3-11-21, 11.49 PM.xcarchive/Products/Applications/Twinkle.app: explicit requirement satisfied I guess I'll try uploading again.

I had the same issue. I checked my developer program settings to see if there was any problem. Went to Profiles https://developer.apple.com/account/resources/profiles/list. For some reason, the needed profile was marked "Invalid". I clicked Edit, then Save. It was shown as Active again. Made a new archive and uploaded, it worked.

Has anyone gotten Mailgun to work with these DKIM instructions? If so do you have any advice? Per the instructions in Domain settings DNS records, we have a TXT record with host=mx._domainkey.somedomain.site, value='k=rsa; p=long base64 data' and there is a green check indicating it matches on the Mailgun settings. We also have the SPF record. On the Apple portal side, the page where we 'Configure Sign in with Apple for Email Communication' (https://developer.apple.com/account/resources/services/configure), it shows a green check for SPF, no mention of DKIM. We have not received the failure report from Apple yet. We're using nodemailer to issue the mail to Mailgun.

Whoops this is a duplicate of https://developer.apple.com/forums/thread/677485 asked just a few days ago (also no answer yet)

Update from the author: we submitted the app with a 14.5 #available check, it was accepted.

I also applied on two separate occasions. After months had passed the first time and I almost forgot about the whole thing, I remembered and went through the form again. Strange that you can fill it out again, right? Does that imply that they didn't approve you and didn't tell you about it? Anyway, followed up after the 2nd time by filing support request. Got this: The teams who review the App Store Small Business Program applications will contact you as soon as your application review is complete. Please make sure that you have accepted the latest paid application agreement in App Store Connect. It seems to me like Apple made the whole thing for publicity.
