Hello, we use apple ID as a sign-up/log-in method, when we released our appstore version, did the switch from beta to market app. Our bundle ids have changed, now we are wondering that is there any way to help users to reach their old accounts using the market app with a different bundle id or any smart idea to approach to to this problem
Hi @Bogaz,
Sign in with Apple uses identity tokens and private email addresses to protect user data. The user ID and private email address are team-scoped and shouldn't change as long as the app is still associated with the same developer team.
If the app has changed teams via an app transfer, then you are expected to perform a user migration to receive the new identifiers associated with the new team account. Please let more about that process below:
