It’s plain deceitful to say jellyfin is simply better. It’s simply less capable and less supported. I don’t know if you’re trying to deceive others or just yourself.

Here’s the difference: With Plex it’s trivial to invite other people to watch content from your server, they can view it on just about any device they have and it doesn’t take any complicated networking setup to achieve. Likewise, just as you share your server, you can view content from other people’s servers through the same interface. This is not a small feature it’s the primary feature of Plex, it’s what sets it apart from xbmc or any media center software.

I am totally on board with FOSS and I would absolutely use jellyfin in a second if it could do the things that Plex does. But it can’t.

As a side note, this new interface for Plex on mobile is absolute shit, a big step backwards. If I had my way I’d still be using the Plex app from 2016.
