Is there a way to retrieve the CustomID?
I am trying to resolve a situation where you could recover your account on a different device using GameCenter. But I also don't want you to be required to play the game if you do not have gamecenter. So the logic would be if you have a GameCenter see if user exists on PlayFab linked to that game center. If so pull down the CustomID that was linked when the account was created. They may sound a little convoluted but I have an entire workflow thought out for this and am trying to fit playfab into the flow.
