I updated my sonos apps and system as required by you Sonos and since that time I cannot access any of my sonos system from any iOS devices fortunately it is still working from my windows PC so I know it is working. Tomorrow I will try uninstalling and reinstalling my iOS devices with the Sonos app. This is unacceptable you make great hardware and terrible software. If this were the first or second or even third time this has happened, I might overlook it, but this happens all too often. The fix always involves some complicated hoop jumping to get the system back to working order. I have other things to do with my time other than to test your software. I will continue to not recommend your products to friends and family. I so very much want you to be better than you are sonos.
