Email Delivery Issue for Private Relay Addresses

Hi Community, We've implemented Sign In with Apple in our application. Our domains are properly registered in the developer console, but we're experiencing inconsistent email functionality with Apple's privacy email service.

Some domains work correctly while others show delivery problems, even though all domains have identical configurations. Apple's console displays green verification status for all domains, yet testing reveals that emails to privacy-protected accounts don't arrive as expected.

We're using SendGrid as our email service provider, and all domains have valid authentication records (SPF, DKIM, DMARC) in place. Has anyone encountered similar inconsistencies with Apple's privacy email service? Would appreciate any configuration tips or troubleshooting guidance. Thanks.

It looks like the issue resolved itself, ran another set of tests today and the emails were able to reach inbox for domains that were having issue.
