There can’t be much positive said about the new app, just watch the threads in this community and other relevant fora.
On my OnePlus Nord CE 5G, the app most often just shuts down within seconds. When it does start, it knows nothing about my system. (clear cache sometimes helps, uninstall/reinstal also tried)
I am a loyal Sonos customer with Sonos Arc Sonos Sub, Sonos Move, and Sonos One, and I feel the value of this big investment is drastically reduced without a working app.
If you insist on this complete redesign of the App, why don’t you introduce it as a new app, and see if it catches on with the users, and leave the old version in maintenance - or perhaps make it open source for people to maintain in a democratic way.
