How do I change from Fb login to Apple ID login

I have been using fb to log in. Would like to switch to Apple ID… anyone done this

no, once you have linked the game to either Facebook or Apple ID you cannot switch

I’m wondering if support would have an idea, have you tried putting in a ticket?
I don’t think it’s possible, once the game is linked one way that may be it, but don’t hold me to that.
You can contact support by logging on to the game, click your profile picture and than click help and start a ticket that way.
