After updating my applications last, Facebook being one of them and the one that I'm having issues with. After the app icon there is now a circle with a number 3 in it that will not go!! Its orange/red colour and it over laps the top right slightly. I've tried removing completely and installing again with no help. Also may I add it's not because I've unanswered notifications because I haven't! Is it an android bug? Or Facebook bug with the last update? Any help gratefully appreciated.
