I play Spotify primarily through Sonos, which I use in four different rooms, and control over four devices. I routinely make changes in volume, music selections, and room use on all devices, depending on where I am in our house. I often get this message: "Playback from Spotify was stopped because playback was started from another room or device. Spotify limits the number of simultaneous audio streams you can access from its' service." Is there a solution to this problem? As I premium user, I expect more flexibility, and assume I'm not the only person with this problem. Can someone help me solve this? Thanks.
