There was an unofficial option for rollback - I’m on Android so I went to apkmirror and downloaded the last good version and turned off auto update. This worked for a while, but then they forced me to update - it literally said I had to update to continue using. I’ve seen someone say this wasn’t actually a forced update, but rather keeping all the parts of your network in sync. I have one Sonos device and my phone is the only things that connects to it??
