My Sonos will no longer recognise one of my Sonos Connects. When I try and add the Connect again as a new device the app tells me “App Update Needed” (the version of the App on my phone is 11.2.8). When I attempt to update the App I get an error message “Update problem”. The associated error code I click on more information is 1101.

I have rebooted my router and wifi. I also also uninstalled the App and reinstalled it. I have also tried doing the update from my iMac. Nothing has worked.

Does anyone have any suggestions?
