Welcome, and thank you for becoming a member of the King Community! I will be very happy if I can help you.
You can sync the game once with Facebook and you did it already so you can't do it a second time.
Try to remember, maybe you synced before with another Facebook.
If you have any questions at all, I’d love to hear from you.Simply reply back to this post, or send me a message.
Have a good day.
