I have two One SL speakers (Living Room and Bedroom) and up until today have been able to listen to Spotify on both at the same time. Now all of a sudden I can only select one or the other. I can still listen on both speakers via the iPhone Music and Podcast apps, the problem is only with Spotify (a service you have to add - could this be part of the problem?)
I opened the Sonos app and only Living Room was showing in the system, and it couldn’t find Bedroom to add it. I messed around rebooting and connecting to another speaker in Spotify then noticed that my system was now showing Bedroom only, Living Room was gone. This has happened a few more times as I’ve gone through various troubleshooting methods (pressed the button on the back of the speaker, rebooted my router) - each speaker alternates showing in my system, and it doesn’t seem to to based on which is connected to Spotify. Right now I’m connected to Bedroom and it will play, but Living Room is the one showing in my system.
Why could this be happening all of a sudden? I haven’t made any changes to my system or WiFI, however I did update the Spotify app yesterday.
