There are a lot of post claiming that Android is having severe issues with the Sonos app. Granted there was a bug that caused the app to crash on Android (approximately 2-3 weeks ago). That appears to have been fixed.
I’m an iOS user (iPhone 15 ProMax) however, I wanted to experience the Sonos app first hand in Android so I purchased a Galaxy Tab A9 plus 11-inch 2024 model. It a relatively inexpensive model compared to other Android and iPAD tablets and/or devices.
My iOS is running 17.6.1 and Android is on Version 14. The Sonos App is 80.06.03 and 80.06.04 respectively.
My iOS device and Android devices both mirror the same in the Sonos app. It doesn’t matter on which device I make a change; the mirroring is not lost.
