Playback Error This Live TV Session has Ended

This issue looks like a regression of: Live TV keeps stopping - #50 by sa2000 on desktop browsers.

Also have “Use alternate streaming protocol for video playback” disabled (which was the workaround discussed in above thread), and I can reliably get a ‘ended tv session’ within 2 minutes.

Logs show ‘idle subscription’, and the dashboard doesn’t detect the live tv session. On android app all works fine.
