I've been hearing bad things about the updated version of the app, except I wouldn't know, because whenever I try, it says 'installation failed.' Any ideas why that is? Also, as of Friday, my notifications will not refresh. I get: 'Cannot retrieve notifcations. [Parser error. Unexpected '_' at position 64) Any ideas there? And if not, what's the best Facebook app for Android apart from the half assed official one?
