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
