This problem began a few weeks ago, where:
Tag Sources - Cover Art... fails to return the cover image and/or populate the image object in the Tag panel. This occurs for both Discogs and Musicbrains queries.
I don't know if this is related, but I have the Tag panel configured to display " Website" and when I attempt to retrieve the Cover Art, this Website object gets populated with the Website link that contains the Album Art, but alas the actual image is not returned.
Any suggestions/help with this issue would be much appreciated. Thanks
