iOS 8.4 Item Has Not Been Purchased
Before I upgrade my iPhone of iOS 8.3 to iOS 8.4, I did buy a few music from the iTunes Store thru my iPhone but after I upgraded my iPhone iOS to iOS 8.4. I could not 'make available for offline' and play my purchased music and it stated as "Item Has Not Been Purchased - 'Kill You (Eminem's Song Title)' cannot be downloaded because it was not purchased with your Apple ID. The thing is I purchased using the same account but after I upgrade my iPhone iOS. The option has become invalid.
What should I do now? Apple has forbidden me from downloading my purchased music awhile allow me to download thru Music Subscription. The system has misunderstanding between purchased music and music subscription.
iPhone 6 Plus, iOS 8.4, Music Subscripation
