How do I get to view MY CHANNELS on my LG TV

I can see my channels when I open PLEX on my computer, but when I want to watch them on my LG smart TV I see nothing. I don’t see a way to build a list as I did with movies TV ect. Any help? Remember I’m new to all this.

I can’t help you troubleshoot this, but there is a forum for the Plex app on smart TVs like LG. You may get more knowledgeable help if you post your question there.
