Hi @Casper686, thank you for reaching out to us and welcome to the Sonos community. I appreciate you for letting us know about your concern. I’d be happy to help you out here. First I'd like to ask questions to isolate the issue so we can create a path towards resolution.
1. Do you experience this in one music service or in all your music services?
2. Does it happened if you try another mobile device?
3. Have you tried force closing the Sonos app from your iOS or Android device?
it would be best if you can submit a diagnostic report of your system for better understanding and see what would be best for the setup. Reply to us with the confirmation number. We and the community are always here to help.
