Currently all my players login to Playfab using DeviceID (Mobile) \ CustomID (PC).
Some of them link there account with Facebook \ google.
If they connect to Playfab from different account (tablet \ iPad or another PC) and try to link the new account to the same Facebook \ Google. i want to be able to let them the option to load or data from the old user and unlink the old account and link the new account.
how do i do that?
