Hi
We are distributor of Antipodes Audio in The Netherlands and we experience the same problem.
The only thing what solves the problem is deleting roon cache in the Antipodes Audio webinterface.
But as you said, after 1 or 2 days, it is back.
My guess it has something to do with Tidel, what we use here.
Also because, when the problem is there, we also cannot find albums on Tidal, to play. They just don’t show up.
When we add an Tidal album to our Library, it works, but then, the next day Roon cannot scan these files.
So we suspect a problem with Roon and Tidal but we are not shure.
We thought it was caused because we use Tidal on a couple of servers, but it seems that you also have this problem and you use only 1 server.
Do you use Tidal?
Kind regards
