If there's one thing that Sonos knows right now, it's that it absolutely cannot mess up another app update. The debacle of its new app still haunts the audio brand a couple of years on, which explains why its latest big update has been more carefully tested and deliberately launched than any other I can remember.
If you're on the latest version of the Sonos app you can now test it out before it goes live for everyone at some point down the line, and I activated it to see what it offers up. The option is called "Enable Improved Navigation" in the Settings menu if you're keen to see it for yourself.
