Help! One of my Echo groups has stopped playing, and I can't figure out why or what to do.
Background: I have groups set up for Bedroom, Living room, Kitchen, Bathroom, and Everywhere.
The Bedroom group has stopped working. (Just to pre-empt any common sense suggestions: I've rebooted the router. I unplugged and replugged every device in the group. I changed the name of the group. I unchecked and then rechecked every one of the 4 devices in the group on the Alexa app.)
When I ask for music on the Everywhere group, the devices in the Bedroom will play. Every other group is working fine. It's only when I ask for music just in the Bedroom group those 4 don't play.
Meanwhile each individual device in the group is working fine. They will play music or give the temperature, etc. if I specifically speak to it.
Any suggestions as to what's going on, and how to fix this?
