Different music in different rooms- Sonos

[Mhayli]

I have a Spotify premium account (Individual). I generally use the Sonos app to play music from Spotify on my Sonos speakers.

Since I have had this set up, I have been able to play different music in different rooms. However, when I now try this, it will only play Spotify content on one speaker, and stop playing any other speaker with Spotify content. The message ‘Playback in (room) was stopped. Spotify is being used somewhere else’.

Anyone else having this problem? Only saw it for the first time last night. Have Spotify changed their terms and conditions?

Thanks.

So, what was the solution? This still doesn't work for me? I have family spotify, with two accounts linked to Sonos, but can only play one song at a time as the original speaker stops if I try to play on another account on the other spotify account. Why is this?
