I have an interesting phenomenon with using multi-room music. Just wondering if anybody else experiences it or if you have any ideas of a cure. I have three dots, one with a Vaux speaker, set up in various rooms in my house. When I ask Alexa to play Pandora or Amazon music on the group, it will play 2 or 3songs and then just stop! I have to give the command all over again. If I do the same thing on just one device. It plays fine. if I ask her to play a radio station on the group it plays forever! Any comments or suggestions as to how to cure this annoyance! Pandora is my most played radio station and I really don't want to have to keep re-starting it!
