How to Refresh the Display and Information in Any iStore
Apple offers three iStores on iOS: the App Store, the iTunes Store, and the iBooks Store (within the iBooks app).
Occasionally, you may find that the information does not display propers or is out of date.
You can reset/refresh any iStore by quickly tapping 10 times on any icon along the bottom of the store. When you tap the tenth time, the store will reload the screen and refresh all of the information.
