Hey,
There are two apps, App A and App B. Both apps do not have Sign in with Apple configured currently, so there are no Sign in with Apple users to transfer. I want to configure this for both apps.
App A is on developer team A.
App B is on developer team B.
They are not on the same developer accounts.
It is my understanding that both accounts need to be on the same developer team/account to get the same unique identifiers (e.g. sub id and private relay email address) for privacy reasons.
Desired Behavior: When a single user logs into either app A or app B with the newly exposed Sign in with Apple functionality, I need apple to return me the same unique identifiers (e.g. sub and email), so that I can uniquely identify the same user across app A and app B.
How can I do this without ANY customer impact.
The only way to achieve this behavior is by transferring one of the app to the other developer team. As you said above, the user identifier and private email address are team-scoped and each developer team will receive a unique value for each. They cannot be used or mapped across development teams.
