Facebook login issues

Theros

Each time I start the game, it require a Facebook login and when I enter my credentials, it refers me back to Facebook login in internet browser. After that, it requires my Facebook credentials with "you have already authorized...). I have to log in 3 times before I get to play the game and Its getting annoying.
The game use to log me in using my google account. But since I decided to log in with Facebook to see how that works, I've been getting the issues above.
How do I resolve that?
How do I make the game not request facebook login?
thx
