I'm having problems with album art in my exported MP4 files. In earlier versions of Audio Cleaning Lab, I've had no problems importing album art under the Tracks ID tab, and having that art included in the exported MP4 files. In this latest version, the album art doesn't seem to be included in the exported files. I've had to resort to loading projects into earlier versions of Audio Cleaning Lab to get the album art included in the exported MP3 files.
