Thankfully you can revert to a previous version of Sonos for Android

First, before you uninstall Sonos from your Android make sure auto updates are disabled

Uninstall the offending app

On the APK Mirror site:  https://www.apkmirror.com/?post_type=app_release&searchtype=apk&s=sonos

choose a version - I reinstalled v16.1:   https://www.apkmirror.com/apk/sonos-inc/sonos-for-android/sonos-for-android-16-1-release/

It immediately found my system including my rooms, services, NAS music library, TV, playlists, stations
