Oh wow, TIL about Wholphin. I'll have to give that a try. I wonder if this will finally resolve the issue with me having to login to JellyFin every few days for no apparent reason (it's not the server, I switched from Win to Linux and same problem).
EDIT: all that remains for this stack is a good browser that can allow usage of uBlock Origin. BrowseHere is a pain to use with its constant nags about allowing pop-ups on certain sites...
Try Fulguris:
https://f-droid.org/packages/net.slions.fulguris.full.fdroid...
It's a fork of the original AOSP WebKit browser, which I've found to be much faster than Chromium-based browsers, and you can import your uBlock Origin filters.
Something is wonky with your setup... My Jellyfin apps stay logged in indefinitely... Phones, TV, pretty sure even my browser is perma-logged-in.

I only get shown the login prompt when the network connection to my server isn't established yet. I'm on Wi-Fi and need to wait for the connection before launching the client.
