iBooks keeps crashing after upgrading to iOS 9
After upgrading my software on my iPad 2 to iOS 9.1 my iBooks keeps crashing. I can't even get it to open. I have tried all resets, restored factory settings and none of it worked. I have also noticed that my Apps store doesn't work properly after upgrading. I can't purchase anything from the store, it crashes as soon as I find the app I was searching for. Any help would be greatly appreciated, I have been frustrated with this problem for over a week now.
iPad 2, iOS 9.0.1
