ahh....I love the smell of a stack of sketchily placed animals in the morning!
My problem has been when I try to integrate with Facebook it crashes every time.
Back to your issue. In the bottom left of the Kairn home screen is the Facebook icon kinda breaking through the ice. Touching that should toggle Facebook on and off(shaded).
problem solved. Since I don't use facepalm, I had no idea what that button did...nor wanted to. I have never seen the FB on/off feature in an ios app before.
