The third of my iPads in my set-up is refusing to allow access beyond the initial 6 songs, and the message comes up that "In-App purchases are not allowed" when I go through the process of upgrading to full status, then pressing "RESTORE PURCHASES". This iPad is older being Version 5 with iOS 16.6 and is the one I was hoping to use for screen lyrics.
Any help appreciated once again. Cheers.
