When did you first download the new App?
Do you frequently power off your speakers.
Have you spoken to Sonos support?
Many of us are experiencing the problems that you mention but you seem to be suffering from a very extreme case which may mean that you need to take time to make sure that all of your Sonos speakers have the latest firmware and that you are using the latest version of the App.
I’m having the same issue with my Sonos Beam. It’s an issue I’ve had in the past but was resolved when I updated the build on the device. Now it’s back
If you are on the current app check the firmware level on the Beam it should be:
Version: 16.5 (build 82259204)
I am experiencing the exact same issue. Sonos as a company is broken.
