Yeah..nah.
Jellyfin works perfectly for me, other than DLNA which is trash for some reason and I don't really need anyway.
I've never found DLNA it to be 100% reliable on any server or renderer I've ever used, so I use LMS for music and Jellyfin only for video.
I would like to find a media manager which can do both, but Emby still doesn't provide this based on my testing.
As such I've already given up on Emby as when streaming music remotely (over cellular in my car) it plays a couple of songs and then stalls, Jellyfin doesn't have this issue but I use Symfonium for remote access to my Jellyfin library anyway.
The features the free version of Emby are missing which I use in Jellyfin are hardware transcoding, live TV/IPTV, and song lyrics.
I'll certainly consider switching and paying for Emby if Jellyfin dies for any reason.
