First, I'd like to ask questions to isolate the issue so we can create a path towards resolution.
1. Do you experience the same on other music services?
2. On which speaker do you experience the issue? All or specific?
3. Do you experience the same if you play music directly from the Music service app? AirPlay?
4. Have you tried removing and re-adding Spotify music service on the Sonos app?
5. Have you tried using another mobile controller? Did you encounter the same?
6. Are you using an iOS or Android device? What's the software version?
Let us know how you get on with the advice above and run a diagnostic report. Kindly include the confirmation number in your response for us to check.
