I've just updated my Apple TV 4th Gen to tvOS 10. Since doing this none of my files will play in Plex. After a few minutes of playback i get an error message saying that Plex can't find the Plex Media Server. I've checked my network connection settings and they are fine (full signal). I am running the latest version of Plex on my Apple Tv (no updates showing in the app store) and my PMS is running version 1.1.4.2757. With the previous version of tvOS (9.something) it happened too but only once or twice a week.
Any help given to fix this will greatly welcome.
