I am trying to get my first app approved and keep getting denied. In my app, I allow for Sign in With Apple. This allows the user to use Hide my Email to give a temp/private email. That is fine and I accept it. One of the major features of my app requires that parent's confirm their real address in order to see information and communicate about their children. It's a sports/coaching app. Coaches create their roster and associate parents with players via email address. Those parents then login and see their list of players (children) and can chat with the team, get schedules, etc. Without the real email, I have no way to validate that parent should have access to that player's details. It has to be secure. And a parent won't know their Hide my Email address ahead of time in order to provide it to the coach.
Apple keeps denying my app saying that I cannot ask for their real email. I have explained it and the reviewer never addresses my explanation. Just denies it with the same reason.
What can I do?
