I recently bought an ipad air and updated it to the current update (8.1). Using ibooks in list view, every second or third time I close a book and return to view the list, the whole screen goes blank for about half a second and sends me all the way back to the top of the list. I have many books so this is very annoying, but i don't know if it's the new ipad or the update. Is this happening to anyone else who has downloaded the new update? Or do I just need to take the ipad back to the store to get fixed? I have tried closing ibooks and reopening, shutting down the ipad and rebooting, and I even tried restoring to factory settings, it's still doing it. Thank you for any help or advice you can give.
