Maybe that has to do with the iPhone? I'm not having that issue with the Android app. I know on my iPad, there is an annoying "undo" on the keyboard that I'm always accidentally pressing when typing a long message in byc. But, that is a new update to the iOS.
I just loaded it. Seems to work just like it does from the browser - except that you can see the little circle mentioned above while the page is loading. But, it loads quick enough. :thumbsup
