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
I can only tell you that personally I'm interested in trying out Navidrome because I don't like all my eggs in one basket (Jellyfin is more complex sw for sure too) and I think I'm not the only one caring more about my music collection than movies and tv. But I did try Jellyfin for music (not with my main library) and it works very well, Finamp on android has offline mode which I find almost essential.
