Is there a way to refresh or rebuild the artwork cache? I am using Asset with the new Naim app for my NDX 5S streamer and on the artist page of the app it is showing artwork that is at least two weeks old. I know that because I altered an album cover and it's still showing the way it was before I altered it. Opening that album and the altered image is there. I have Asset set to not resize artwork and also to upstream it. Changing either or both of these setting doesn't change the situation.
