When I had sync issues I followed the steps below, I just changed Chrome to Safari though since you're on iOS. 1) delete the Facebook app.
2) go to Settings, scroll down to Facebook, open and select where it says "your name", then delete account (Ignore the disclaimer it is not important)
3) restart your device.
4) open Safari and go to Facebook.com, sign in to your Facebook account.
5) Open the game and select connect. This will automatically bring up Safari and sign you in.
Once you are connected again you can re-install the Facebook app.
