Device TV: Android 11 Stremio Device: Fedora Linux with Flatpak stremio

Sorry about the issue but you can install Stremio directly on your Android TV and play something without casting.

The TV's processor isnt too good but I set up a server separately and used that with the android app on the TV.

i could only think about flatpak sandbox causing this not sure if there is any workaround
