By pointing out that everything that you say HAS been done... and Apple continues to ignore the issue.
Unless you subscribe to Apple Music, which DOES cure the issue.
Your contribution is telling people to do something that has been proven to not work in this case.
Again, read the multiple threads on apple discussions and here. Using the apple feedback BS has been done, does nothing to help the issue. Some artist pictures are missing in itunes for over a year, Apple Music sub fixes that issue... and yes, feedback has been sent.
The issue has been going on for YEARS as I pointed out.... so in your mind NOBODY has ever thought to contact Apple? Apple has ignored the issue, so people branch out to find other forms of help. And unless you bow down and pay a sub to Apple, your playlists and artist pictures of music YOU OWN and has nothing to do with Apple Music... gets screwed up.
I just come here from time to time when I have an issue because MR tends to have a lot better results.
Been done.
Proves my point.
Again, It's been reported for years. Apple Music was created mid 2015, note the date these issues started popping up.... right afterwards. Note that if you Sub, you do not have these issues...
