Hi there @cRoy30, thanks for the update, and sorry that I overlooked the diagnostic report that you’ve sent. Upon checking, all seems to be normal on your Sonos system. This needs to be checked further by our team, I'll ask you to kindly contact our phone support team for further assistance and more in-depth troubleshooting steps. They may request for screen share or remote access to your device controller to check on some settings and configurations on your devices. 

Let us know how it goes and we're here to answer any further questions you have.
