iOS 9.3.3 broke iBooks store on iPad
After the 9.3.3 iOS update (7/19/2016), the iBooks store will not open on my iPad Pro 9.7, nor will it open on my iPad Mini 4. My books works fine, just the Featured, Top Charts, etc. will not open. iBooks works fine on my iPhone 6S and iMac.
iPad Pro, iOS 9.3.3
