The last few TV Shows I have watched, the Plex app has stopped playing before the end of the show, missing the last few lines of dialog when end credits are played during a scene.
I have checked the same files using Plex on an iOS device, and the end of the show is present there (along with the production company logo afterwards)
It looks like the TVOS app stops when it sees the end of a file, and doesn't play out the last data from the buffer?
Using latest Apple TV and Plex server (OSX)
