Hi @Minerva,
Thanks for your response and for submitting the diagnostic. Upon checking the report, there's no issue found in your Sonos system and it's up-to-date.
Let me suggest the next troubleshooting steps and see if it will work for you.
- Uninstall the Sonos app on your Mac computer.
- Download and install the Sonos S2 app by clicking this link.
- Once installed, open the Sonos app and connect to your existing system.
