I'm trying to add a device while music is playing on the Hub. I select the cast icon in lower left corner and it lists all available speakers except one. The same device shows up in the Google Home app, but not in the Hub.
This also happens when the missing device is playing music with other speakers in a group. When I select the cast icon, it lists all the playing speakers except the one device.
I can see and control speaker groups that include the missing device - but not the device by itself.
Appreciate some help to either add it or make it visible.
