Playback issue on Android TV app

[ezrab552]

I don't know, maybe this is android tv 11\google tv ui fault?

This is of course possible but it can't be Android TV 11 alone since this is what I got too on two TVs without issues. To be honest, I've got lots of issues but interrupted films is not one of them.  

Since your other device works it most likely has got to be something on the new device. Maybe there's a background service running that eats up CPU, maybe it's running out of RAM, maybe the system needs an update, or maybe it's even running an update that can't complete for some reason but takes resources away from the Jellyfin client, etc.

I checked everthing I could think of. No idea what to try next.
Edit: I tried to play movie with MX player via local network and still, the video not playing smooth.
