Consider the following scenario. The user is registerd in our app and/or backend with his Apple ID. Then the user requests to be deleted. We delete the users an all of its details. After some time the user decides to come back to our app. How do we make sure that we can get the mail and first/last name next time the user requests to register since here https://forums.developer.apple.com/message/374403#374403you claim that this happens on the initial login ?
In that case does it make sense to revoke access of my app to the user's Apple ID in order to trigger to retreival of the mail and name again ? If so how ?
