I have a Roku 3, Fire TV 2, Apple TV 4 and a Shield TV.
Recently, I added about 70 episodes of an old TV show to Plex. On all of the devices (except the Apple TV 4), when I look at 'Recently Added' for television, all of these episodes, over multiple seasons are all collapsed into a single poster (which is what I want) and right next to it, are episodes of different TV shows.
BUT, on the Apple TV 4 Plex client, when I look at Recently added TV shows, it has the single poster for the episodes of the old TV show I added but nothing else. This a problem with the Apple TV 4 ver of the Plex client?
