Well I already have jellyfin running in a container, just have to figure out how to get mum's TV to work with it I guess
log in on a local IP and not the network name and it's working again. but I'll be moving to jellyfin from now
And sharing my libraries with other friends sharing back with me is pretty great.
This feature is imo THE killer feature of Plex, although I use Jellyfin. There's no sharing of libraries like Plex does. Multiple user accounts per server, yes, but you have to switch between servers and search separately.
