I'm relatively new here but I've been making my own explicit tags for about two months now with Mp3tag and just updated to v2.91 today. Since the update, Mp3tag saves my ITUNESADVISORY field with a value of 1 to create the explicit logo but when I drag and drop the updated tags into iTunes, nothing changes. I've tried multiple times and restarted iTunes hoping it was just lagging. Is there an updated way of exporting the tags to iTunes since the update?
Update: No issues now. Oddly, I now have to play a song for iTunes to recognize the change. It won't automatically update anymore
