You unfortunately lose Widevine support when you do this though (either switching to LineageOS or a mini-PC). That means you can't stream any of the mainstream services in anything like a half-decent quality.

It's very unfortunate that every streaming service has given up on supporting anything except Google-fied Android and Apple iOS/tvOS. I dont like the services to begin with, but a fully Jellyfin stack can only get you so far when there are niche requests involved as well.
