I have no problem dragging songs that predate the upgrade, but am unable to drag any song added since I upgraded iTunes to version 12.1.2.27. Any way to fix this?
What program are you using to work around iTunes to get songs onto your Android phone? Possibly that program needs an update now that you have updated iTunes.
I'm just putting my card into my laptop which shows up as 'Removable Disk F' and dragging the songs from iTunes onto the card. I just updated iTunes again to 12.4.1 but the problem persists.
