Cant connect to facebook

I love this game, I play it on my laptop all the time, as its addicting and a little different from all the other connect and match games. So when I was ecstatic to find an app for it, but it wont lemme connect to my Facebook. Fix please because this is an excellent game that i would love to play on the go.
