Recently Google cast groups were enabled to include Sony devices. Creating groups works great with my Google Cast audio devices, X88, X77 and a dn1060. It's an amazing feature. Using any combination of these devices works in Google play but in spotify groups disappear as soon as the DN1060 is included in a group. Groups reappear when dn1060 is removed. Is there an explanation for this or can you work with Spotify to resolve the problem?
