The title says it all. Some of my channels are missing on “Live TV and DVR” on the Roku. They are also missing on Android. But they are there on the web service and on the W10 app.
On Roku - in settings - I have hit “Refresh Guide”. I do not see this option on Android.
Someone also opened a ticket on this and it is the same issue.
"Mobile and TV devices will not show any channel that lists “Unknown Airing” in the guide. This happens on Roku, FireStick, and Android. The current work around is to tune to the channel under your account on Plex Web then it will show up under “What’s On” ‘Recent Channels’ and it even knows the time left in the Airing under What’s On on the devices that the Channel won’t show up.
