You can unpin it, but it’s still doing whatever it’s doing in the background.
Since it’s release I’ve noticed Plex using more resources than usual every once in a while when it should be idle. Checking plex shows that it isn’t doing anything, or shouldn’t be. There’s no scan, no one watching anything. Nothing. Then why the sudden 30% CPU usage?
Whatever it’s doing in the background is because of “Discover,” which I don’t need or want.
