Hello Apple Developer Support,
I am experiencing an issue with Apple Sign-In and Private Relay across two separate organizations.
I have a web application that supports Apple Sign-In, configured under organization ID: 62P86SVLK4. Users can log in using their Apple accounts with the Hide My Email (Private Relay) feature enabled. This web application was created a long time ago and initially only had a web component.
Recently, we developed a native mobile version of this application, which also supports Apple Sign-In. However, due to business constraints, the mobile application was created under a different organization ID: T6JT35U9NW.
The Issue
Since the web and mobile applications are registered under different organizations, accounts created using Apple Sign-In with Private Relay are not recognized across both applications.
For example:
A user creates an account in the web app using Apple Sign-In with Private Relay. When they attempt to log in to the mobile app with Apple Sign-In (also using Private Relay), authentication fails because the generated Private Relay email addresses do not match between the two organizations.
Question
Is there any way to link Private Relay accounts across these two organizations so that users who signed up on the web application can log in to the mobile application seamlessly?
I appreciate any guidance on how to resolve this issue.
Best regards, Kamil Gronert
