Be prepared to wait , I put a question on their support page , 3weeks later they mailed me asking had I been helped I replied NO since the radio silence, another 3 weeks
Im more surprised since the tech guy from USA, Jimmy, said to me that it was not going to be certified. Dead flat. The reason was they wanted to get people use their app and “maybe a compatibility issue from the new systems”.
Perhaps they reconsidered after getting many puzzled requests because the Naim Mu-So v2 already is Roon Ready, so it doesn’t seem to be a lot of work (as most likely they all use the same streaming board). Who knows
