Hi, yesterday I posted pretty much the same thing happening to me, but I have an Innuos server so I posted it under #audio-gear-talk:innuos . It was suggested I move it to #support , which I have. Here is the original post. I’m having the exact same issue since the latest Roon update. My local files have vanished from my Library. Only Tidal files remain. And I am also experiencing that weird issue where tracks in playlists are appearing as ‘Unavailable’.
