I was having a couple of issues with Plex on an older version - the thumbnails wouldn't properly load on ATV and when you tried to play any media it would either say 'accessing trailers' (or words to that affect with a spinning loading symbol) and then basically time out, or it would throw a media error. Prior to this, it's been fine and I've not changed any settings.
So I decided in my wisdom to update PMS to the latest version. I can get into Plex fine now via trailers on the ATV, but it says 'plexconnect no plex library sections' if I go to the settings I can see it finds one plex media server, I can sign in as my ID and also in the one below that says home, so they both have my ID but I still get the same error. Also, after I've signed in, I notice that PMS found changes from 1 to 0, so I'm not sure if that's connected?
But yeah, I can't access my library. I downloaded the app for android on my phone and it streams content from my PMS like a charm.
Thanks in advance.
