Honestly, I am not sure if this is an issue with all Store Apps, but it IS an issue with Netflix. I like to binge-watch shows and I'd like to use the Store Netflix App, but the problem with it that started only a few updates ago is that after an episode ends and the next one begins, Netflix App resizes on its own back to window mode (as in rather small window in the center of the display, not maximized window). I am not sure if it is a bug... Does it sound like a good way to DISCOURAGE a binge-watcher from binge-watching? Getting off your butt to press the Fullscreen button after each episode IS annoying! Luckily, Netflix playback in Edge does not have that problem, but due to HTPC convinience situation, I would rather use the Netflix App...
