wrong album art on new iPhone SE June 2020

Follow travisiam 's advice from Sept 2019. He has the solution. I spent countless hours w/Apple on the phone but travisiam had it solved. With your iphone connected, go into your itunes music on your computer and find just ONE album with the wrong art from your iphone. Right click on that album and go to songs, find the songs from that album, use the toggle arrow at the bottom to scroll thru all the songs on that album. Then hit apply again. I also hit sync after that and IT FIXED ALL THE ALBUM ART FOR ALL MY ALBUMS! What a miracle after struggling with this for 4 days! PS: I had "selected songs, albums, playlist" checked as I don't need 350 albums on my iPhone.
