The Facebook app (version 5.3 from Dec 13, 2012) running on iPad 1 with iOS 5.1.1 crashes at launch.
It always used to work then I restored to factory settings whilst upgrading to iOS 5.1.1 now it crashes on launch and returns user to home screen. I have deleted the app and all it's data, restarted the iPad and re-installed the app. Other apps from the store and that account run fine, but I'm at a loss what to do next?
