the problem has been going on for the past 3 months.  I have Uninstalled the app and reinstalled with the same issue.  I'll try to capture the exact error code but it generally states that a Sonos system could not be found and to reset/install.  I did that tice before realizing that my wife's iPhone remained connected with no issue

Hi @Sling, thanks for the update and for sending a diagnostic report of your Sonos system. Upon checking the diagnostic information. It shows that your devices are offline. Kindly do a sequential reboot starting from your network connections, unplug it from the power source for 1-2 minutes. And once it’s back online, Do the same thing on your Sonos speakers. Let me know how it goes.

I have EXACTLY the same issue. I rebooted and reinstalled a device today because of this issue, but it has just happened again. I started one of my Play:1 devices playing music through my android device. The Sonos App then lost it completely. My wife's iPhone was able to connect and turn the music off. The device is connected because I can view it through my Omada controller.
