Hello community, In our application, we've implemented Apple ID for user authentication. Unfortunately, we forgot to register the associated domains and communication email addresses. This oversight has led to complications in email delivery via the private relay service. We've taken steps to fix the issue by reconfiguring the domains and communication email addresses. Post-adjustment, new user registrations are functioning properly. However, for users who registered before this fix, the problem persists. We followed the instructions provided on https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_js/communicating_using_the_private_email_relay_service, and we also have SPF configured, which has passed validation in our administration. Has anyone encountered a similar issue, and if so, how did you resolve it? Any insights or guidance would be greatly appreciated.
