I have the Sonos app on my iPhone & iPad Pro. Last night when I went to use my App on my iPhone I get a blank screen on all screens. And on top it say Unable to connect to Sonos: Learn more. But I am still able to use the Sonos App on my iPad to control my music. Both are on the same wifi network. I can check in Settings > About My System and all my Sonos looks to be reading fine. The WM is 0 except for Move > 1. I have sent a diagnostic check. And I wanted to ask here before I try the several steps in the app for troubleshooting.So why is the app working fine on my iPad and not working on my iPhone?
