I have 3 mini nests. All were working fine until a couple days ago. They all recognize various questions & commands except I cannot get them to stop playing music. I will be listening to music and when I wanted it to stop, I used to just say "Hey Google, stop" and the music would shut off. Now it says "I dont understand " and continues to play music. I have tried "off" "turn off the music" "stop playing music" and nothing will work. I have unplugged, rebooted, & done factory resets on all 3 and still doesn't work. And like I said, it recognizes everything else.
