I am running the latest Plex Beta on a Nvidia Shield TV (Android TV). My problem that after a while the app will not connect to the remote server. Typically happens when I close the app, or restart the device.
My solution to fixing this is logging out of my Plex account on the app and logging back in. A complete pain.
Im getting this too randomly. Ive also seen this issue crash my server. Ill get notified that my server is offline, then it will come back in 2 minutes. I noticed this only on my shield. My friends PS4 Pro used to crash my server too.
I noticed a similar and probably related issue: after rebooting the Shield, the previews on the main homescreen of the shield do not load automatically. I have to open the plex app.
However, there is an auto-login option(in the plex app). Maybe this is the solution (currently it is deactivated). I did not test it, yet.
