Thanks for reaching out to the Sonos community. We appreciate you for letting us know about your concern and for submitting the diagnostic.
In the report, there are no showing Sonos devices for us to check. To help you out with this, please follow the steps below.
- Sequential reboot to refresh your network and all your Sonos devices connection.
- Unplug your network devices (modem, router, any wireless access points on the network) from the power and wait for 60 full seconds before you plug it back in.
- Once the router is back online, unplug all your Sonos devices from the power. Please wait 15 seconds before you plug back them back in.
- Force close the Sonos app from your iOS or Android device.
