Used to be good. But with every update to the system and app, it gets worse and worse. Nowadays, we're lucky if the Android app displays two of our seven devices. Everything else on our network works fine, but Sonos... utterly random. It should be easy, seamless to use, but it's not. Not ever. When it comes time to replace these devices because Sonos like to force obsolescence on its customers, I will be looking elsewhere.
