I have 3 Sonos One speakers and a Sonos Move connected to Wi-Fi. My iPhone can connect to the speakers. Music appears to be playing on my phone, the volume is turned up and it appears to be connected to the speakers but no sound is coming out of the speakers (except if I switch the Move to Bluetooth). When I open the Sonos app on my iPhone, an error message appears “Unable to connect to Sonos. Let’s fix it.”  Proceeding through the repair wizard doesn’t fix the issue. I have checked my router and the speakers are appearing as attached devices and they have obtained an IP address. This same issue occurred once before and eventually it resolved itself. However, it is not resolving itself this time. How can this issue be fixed?
