I’ve been running into an issue where the Plex app on my Chromecast with Google TV restarts itself (doesn’t go to the Home Screen, just seems to restart) while watching Live TV, both with my Xteve setup, as well as Plex channels. Looking at the logs (provided below) seems to point to an issue with ExoPlayer. This seems to affect all channels and happens randomly, although consistent after a bit of streaming.
Chromecast is up-to-date, Plex app also up-to-date. Server software up-to-date, as well.
Server Version#: 1.28.2.6151

Tuner Make/Model: Xteve 2.2.0 and Plex Channels

Channel number/Name: N/A, affects all channels
