Hello

I have recently bought both the asset Upnp and the perfect tunes because I had to many albums, where there were something wrong with the metadata or a missing cover.
The first fire or five album where I had some of the issues, perfect tunes solved perfectly. But now I have two albums, where I apply a cover, but it dosn't show, when I open the asset UPnP via the naim app.
What am I doing wrong?

Best regards Sebastian
