Slow, clumbsy, doesnt update

App is very slow to launch. Once open, I often find the back and conversation and back buttons dont work and I have to wait further for them to function. Finally, the app often doesnt update, especially if I read messages on the web. It just sits there showing "4 new messages" when in fact Ive read them all!! Needs better sync!
