Xperia with Facebook

[SYC]

Xperia with Facebook is not working, it won't log me in in set-up, and it also doen't let me add an Xperia with Facebook account.  It goes into the login page, but when I press login, it shows loading but then doesn't register and the account is not created or there is no tick next to Facebook in the set-up.  What should I do?

Based on my Exp, you should install official facebook app and login with it in order to use Xperia facebook.
