Thanks for all the information. I believe I’ve tracked the issue down to a deployment/configuration issue and have a couple fixes.
I’ve deployed a fix in 3.13.29 (this is a server-side update that will not require an update to the app on your device), which should automatically show up once the app is relaunched after the various caches expire, which should be soon. If you’re not seeing 3.13.29 in the next while you could try removing and reinstalling the Plex app on your TV to try and force it to get the latest version of the web app.
Please let me know if you continue to have issues once the web app has been updated to 3.13.29 (as shown in Settings: About).
