I have a new dot 3rd gen and 4 2ne gen and a echo. All worked well until yesterday. The new one, the 3rd gen, 2 weeks old, stopped playing music. Network connection good, tells jokes, answers questions, turns on lights etc. The app makes it look like it is playing music but it is not. That is only part of the problem. That is a member of a speaker group and I would like it to continue to be. When it is a member of the group the music will not play for the group, when I remove that 3rd gen from the group then the music will play over all in the group. If I add this to another group it same thing for that group. It worked properly for 2 weeks now it will not. Please do not suggest that I bounce it, i have done so many times. I have a great network and all other devices are working on that network. I have physically moved the dot to the same location as another and it works except for the music while the one just next to it will work great. The issue is the same no matter if I use the app or a voice command to start the music.
