Game won't load - looping with facebook

Unknown

Up until an hour ago I've had no problems playing the game for over a year on my phone. However, now when I go to load, I get through the screen with silver surfer on, the page goes black, then loads up Facebook, signs in, and then starts the loading process of MPQ again.
What can be done to stop this happening or is it a new bug from the recent update?

I had this happen once, and it turned out that I needed to log out and back into Facebook via my iPhone's settings (not through the game).

Hopefully it's as simple a fix for you.
