I have a single Sonos One speaker and the app kept prompting me on my iPhone to update to Sonos s2. So I finally did, but the new app is a piece of garbage. It freezes up every time I use it. When I tried to delete it and re-download the Sonos s1 app, it keeps telling me device isn’t compatible and I need to “upgrade” to Sonos s2. How can it not be compatible when I was using it just fine until about an hour ago for the past few months? How do I get rid of Sonos s2 and go back to Sonos s1, which had NO issues at all. Thanks for any guidance on this.
