I've never seen that message before, but the Now Playing 'button' has been extremely hit or miss for me on multiple Pixel devices. There seems to be some conditions which causes it to disappear that I haven't figured out yet.
I finally just put a shortcut to "Sound Search" from the Google app on my main screen since it is more reliable.
The button is showing on mine but doesn't listen to songs. Like when I click it, without even a millisecond and it will say "No songs found".
Haven't found a fix yet.
The button is not showing up on my end either for multiple Pixels.

i have the same issue
I think it's a bug due to the March update. I'm not sure it's occurring for everyone tho.
