iOS users: Troubles with Facebook Sign-In?

I have tried deleting both the chess.com app and the facebook app, then restarting my phone and then signing in to both accounts again. I am still getting the error message "Please open IOS Settings ("Facebook" section) on your device to ensure your account is set up and "Chess" is enabled." 

When I go to the settings, facebook section, chess is not an option on there for me to enable. It used to be there, but now it is gone. I think the only thing that may help now is a password. I can login using my PC just fine, but not on my IPhone which is the only place I play chess.

Thank you

You could try deleting the Facebook account in the "settings > Facebook" and starting from there. I don't have the Facebook app on my phone I just do it all through safari

Noted.

I can't sign in to my chess account using my facebook account on my iphone6
