Content is not authorized
When I try to play a certain song on iTunes for Windows, it prompts me to authorize my computer by entering my Apple ID, but after i do that and try to play the song, it keeps telling me to authorize my computer. I have tried signing in/out of my Apple Id, deleting the SC Info folder, reinstalling iTunes but nothing seems to work. I can't play this song on my iPhone 6 either: it displays a message that says "This content is not authorized". Does anyone know how to fix this issue?
iPhone 6, iOS 12
