Our app uses Sign in with Apple. In recent weeks (or months), we've noticed that emails sent to @privaterelay.appleid.com addresses are not being delivered.
We're not receiving any bouncebacks or error messages from the mail server, but the emails never reach the user's mailbox. We've also checked spam folders, with no luck. We have verified that our Email Sources are configured correctly in Apple Developer settings.
Is there any way to debug or trace what might be happening with these messages?
Thanks in advance!
