Spotify Doesn't Connect to all 3 Sonos Sound System Zones

[ChezStephan]

Hi,

We use Spotify together with Sonos Sound System.

With Sonos we have 3 different music zones (the same music list playing in all of them).

Unfortuantely Spotify doesn't properly connect to all 3 zones. The music keeps jumping from one zone to another, but doesn't play  in all 3 of them at the same time.

Please advise how we can solve this issue.

Thanks!
