iTunes Store is not working?
A problems have been occurred
It shows cannot connect the iTunes Store
Have you tried : If you can't connect to the App Store, iTunes Store, or Apple Books - Apple Support ?
But if you are in Hafizabad in Pakistan and are trying to use the iTunes Store app on an iOS device you are likely to see an iTunes U screen in the app and possibly then a 'cannot connect' message - media (music, films etc.) isn't available from iTunes in Pakistan.
