I just tried playing LBC on a different device a Google Nest Mini. Also
tried playing a song on spotify. In both cases sleep timer not turning
off audio. This used to work. Suspect Google has changed something.
The same thing is happening for my Google Home mini. I say "stop playing
in 5 minutes". It responds with "speaker will stop playing in 5 minutes"
but nothing happens, the radio station I'm playing keeps playing. Super
annoying when I'm trying to fall...
