Halo, I am new user of Unity and Playfab. I learn from youtube step by step.
In my situation,
device A > LoginWithCustomID A > linked facebook A
device B > LoginWithCustomID B > linked facebook A (unlink facebook A from CustomID A)
(LoginWithCustomID A = deleted)
device A > LoginWithCustomID C
May I know how to set up a button for unlinking facebook account and delete the customID A with VS code?
