I have the latest update on a new Apple tv 4 and cannot get HBO NOW to work. According to an ebook I bought to show how to set it up, I should be able to go to Series, click on the series I want and a details page shows 3 options at the bottom, + Add Watchlist being one of them. It is not, I have 2 options but not Watchlist. Anybody getting Watchlist to work on their ATV 4?
