I have done what is suggested, but it still does not work. Here are the three main issues with iTouch 6 iOS 12.4.2: The music app must be restarted three times before it actually allows me to initiate. Second, some of the music purchased now just show "vocal" in the iTouch, but on the computer there is no problem. Third, when putting on pause and returning to play, it shows a different artist. Then, once you have pressed played, it cannot play. Fourth, the battery does not charge fully, it only charges to 97% and drains quite fast. I don't know if it is an issue because so many versions of devices; i.e, iTouch 6 Gen, iPhone 7 Gen, iPad 3 Gen, computer still running old OS since it cannot be updated.
