I downloaded a few things thinking I could watch offline. Turns out you can’t. Does the app have a way to remove the downloaded content?
If you want a jellyfin app that actually manages the downloads, letting you both watch and delete the downloads in the same app, try Findroid.
Like already explained, the web-app based clients just download the media files. You can obviously watch them using any media player that way, and delete the files when you’re done, but it makes things a bit clunky.
For music, there’s Finamp (FOSS) and Symfonium (Paid, but really good, and with active dev).
I use vlc, it scans the entire device and shows all downloaded media, after I watch something I just delete it using vlc.
Findroid works if you want it all integrated but I haven’t tried it yet
