My Music Library won't play on my new iPad Mini A17pro

Everything transferred to my new iPad. But when I try to play items from my personal music library, I get a message, 'This item is not currently available in your country or region.' I have a MacBook Air (13 inch, M3, 2024, Sequoia 15.1) & an iPhone 14 (iOS 18.1.1), & all my music works fine on these devices. I tried syncing my iPad Mini with my MacBook Air. Unsuccessful. I have rebooted my iPad Mini. No success. I tried unchecking the 'sync library' option. Still no success. I live three hours from an Apple Store, so a Genius Bar appointment is not an option.
