I’m unsure how to reply. I just now hit the + button to add to my collection. It processed (spinning disc in upper right) and the tracks are unavailable again. first image above.
I’ve not had this occur before, thought it worth noting now.
I closed my local Roon client and restarted it. It still shows unavailable I am listening to it now.
I think it just isn’t integrated properly. Now it won’t add to my library and sits processing. I’ll check back, maybe I’m just impatient as noted.
