Lol, I’m the server owner, so I am expected to pay to allow multiple accounts. Which is my exact complaint.

I had issue with offline usage, and found, with time, it only got worse. My lan clients eventually stopped showing my server unless I logged into my Plex account first. Maybe things changed since, my experience, Plex became overly dependant on a connection to their servers.

To little to late, I’ve since moved to Jellyfin, which solved my frustrations. I have no interest in moving back to Plex.
