I like the idea of Apple's TV app - at least I like the idea of adding multiple shows to an "to watch" list from different sources (netflix, Apple rentals, Hulu etc), aka the "up next" feature. However I've noticed that some shows don't have the "add to up next" button while others do. Has anybody noticed this? There's one particular show on Netflix that I can't add to "up next" while other shows can be added. Is there a known fix?
