Don't know if this has been answered here yet or not, but I sure need help. Everytime I ask it to turn off in whatever minutes, I always get the message of "sleep timer can only be set if there's media playing" even when I have YouTube or Spotify playing. Very frustrating. Not even the "help" links Google sends you to help so I'm hoping actual people can. Thanks.
Haven't tried this myself will give it a shot when I'm home
