Hi, I have a 5 room system setup with boards Up2stream Pro V3. Initially I was able to group all the speakers and from Spotify I could play music on the master, which played on all, or select each individually and play only on one speaker. Since one of the firmware or software updates I can no longer do that. I can see tma grouped speaker in Spotify, but when I select it, it doesn’t connect. Does anybody know how to restore the previous way of working?
