The Sonos app not working well for me, weird regrouping of zones when I don’t want. Doesn’t seem to have impacted Roon thankfully!
So far I have had zero issues with the Sonos App 2. Just setup an Amp to power in-ceiling Klipsch speakers as surrounds. Working fine so far!
Been fine for me but I don’t use much of its features other than its sound calibration things I added two Ikea speakers as surrounds to my arc and all worked fine.
