I don't have any issues with DV on android TV with jellyfin ? What do you encounter ??

No there is none unfortunately, but i'm in the process of making one! For now my settings are these. And i made a quick tool to compare results from a searxng instance to a list of desired results, you can find it here. If you want help with that, i'd be glad to help !! :)

EDIT: more details in my settings example

Searxng with custom engine weights and a proper filter of upranks/downranks domains give me as good results as kagi !

I have some issues making screenshares with the native app. But the browser version works flawlessly.

If you must use windows but hate using it, have a vm inside linux dockur/windows: Windows inside a Docker container.. But it is not the smoothest windows experience (it really is for backup when you really need windows): it is not as fast as directly booted windows and apps that can't run in a vm won't run here. If this does not work for you, then dual boot or just use windows if necessary!

The first option fits me well fyi :)

Yeah I wonder too.
