When I tested Sign in with Apple after completing the transfer of the app, I noticed that when I Sign in with Apple, I became a different user (sub).

After reviewing the document below, I realized that before transferring the app, I needed to generate a transfer identifier and hand it over to the receiving team. https://developer.apple.com/documentation/sign_in_with_apple/transferring_your_apps_and_users_to_another_team

Is it possible to transfer Sign in with Apple users now, after completing the transfer of the app?

I tried to generate generate access token with parameters that indicate in the document below but i can't. https://developer.apple.com/documentation/sign_in_with_apple/transferring_your_apps_and_users_to_another_team

On the other hand, I can generate access token with parameters that indicate in the document below. https://developer.apple.com/documentation/sign_in_with_apple/bringing_new_apps_and_users_into_your_team

I tried to call generate transfer identifier API (/auth/usermigrationinfo with old sub and recipient_team_id) with access token which is generated by new private key, then transfer identifier is generated. Moreover, I tried to call transfer API (/auth/usermigrationinfo with transfer_sub), it was succeeded and generate new Sign in with Apple user id (sub).

In addition to becoming a different sub value, did the privaterelay email also change for the same user from old team to new team?
