Netflix has managed to annoy a good number of its users with an announcement about an upcoming update to its Windows 11 (and Windows 10) app: support for adverts and live events will be added, but the ability to download content is being taken away.
Netflix must realize that it's a huge frustration for people who relied on offline downloads to watch content without internet access: on planes, trains, and campsites, and anywhere else where Wi-Fi is unavailable or unreliable.
There's a small chance that Netflix will change its mind if it gets enough complaints, but the streaming service seems determined to add as many money-making features as possible, while taking away genuinely useful ones.
Let's not pretend that an "average" mobile user is capable of doing that?
Which is why we need to help one another to get there:-).
If we're talking about mobile, the Jellyfin app lets you download to the device already.
If we're talking about laptops, as far as I'm aware, the Jellyfin desktop app doesn't have a download feature.
I don't see that feature listed at https://f-droid.org/en/packages/org.jellyfin.mobile/? I have never used Jellyfin though - it looks quite awesome! - and so know nothing about it, I mention here to say that it might either depend on how you install it or perhaps it's a plugin.
