iBooks On iPad
In iBooks when I switch from My Books to: Featured, NYTime, Top Charts etc. the page is blank. I'm unable view any of the book categories or buy a book.
iPad Air Wi-Fi, iOS 7.0.4
There are a number of other threads about the same problem. Closing the app via the iPad's taskbar, doing a soft-reset/reboot of the iPad, and/or logging out and back into your account on the iPad might fix it (though possibly only temporarily). If you want to leave feedback to Apple about the problem : http://www.apple.com/feedback/ibooks_ios.html
