Remote viewing in Jellyfin requires significantly more work from me as the server admin, but it is just as easy for the remote viewing clients. I don’t have to do any first-time setup for them. I recommend an app or two for the media type they’re using, and all they need is URL, login, password.

Thanks for your suggestion. I spent some time investigating this to see how feasible it would be. I have my own domain and static IP, so setup on my end would be pretty straight forward. Users would need to enter my domain:port on first login, but I could walk them through that. I'm going to give it a shot and see how practical it is. If the performance is better, as you say, then it probably trumps those features you mention. With the exception of subtitles for me and the family. We use subs most of the time and need on-demand selection. Automated subs are very hit or miss.

It's also disappointing to hear the Jellyfin app doesn't support downloads but I guess if Streamyfin is available on all the platforms then I could just use that.

I tried Finamp and the UI is very not good on iOS. It also lacks a lot of features compared to Plexamp.
