How can I delete the iBooks app on my iPad and re-download it?
My iPad is Model ME406LL/A. Running iOS 8.3. Since I upgraded to iOS 8 I can't read any iBooks I previously purchased and downloaded. I can see them and when I tap the book icon I can only see a summery page about the book, I cannot open the book to read. Maybe I should delete the iBooks app and redownload it but I do not know how to do that. I have iBooks 4.2.
