Roon has all kinds of issues with the new 880. A lot. Database issues and “new rules” is affecting many, and those are crucial. I would not sweat it. Let it work out by itself. I feel for you. It’s frustrating.
I am a big Roon fan, but I have a hard time understanding them often times. If it ain’t broken why fix it?
Oh, and if you use “after market” Roon Cores like Innuos, forget about it, they will not help you.
