I have an open ticket but it hasn't been assigned. The glitches like the avatar freezing up and the crashes seem to be fairly common. It super irritating but the lack of full functionality without being on wifi is a ****er. The wall says no one has posted ..it's just blank. Log on wifi and boom...posts magically appear. Visit neighbors...all that. I see no reason why only part of it will work on 4g when this time last week I did it all day long.
