Is the amazon app annoying or what?

I can get into the app OK, I can play videos OK, but I can't get out! Once in it, I'm trapped! It says use the back button to quit, but using the back button just gets me back to a different video. And the dadgum Roamio remembers I was in the amazon app, so if I hit Live TV to get out, then hit the left button (which usually takes me to the TiVo menus from live TV), AAUGH! I'm back in amazon again.

Am I just an idiot, or is it like this for everyone?
