You’re gonna need to turn off auto play or turn on a sleep timer. You already have the settings to turn it off automatically but it thinks you’re still watching.
I have a sleep timer app on my phone that usually works if I’m doing casting if the projector or apps don’t support it.
I didn’t know if jellyfin supports it but maybe a playlist that’s not infinite could function as a sleep timer too.
Is there any other chromium android browser that supports extensions?
