I'm reading a book in portrait orientation. I want to read it in landscape orientation, so I turn the iPhone on its side. But it's now at an entirely different location in the book.
So I turn the iPhone back vertically and it does not return to the original location. (But it does remain at the same location that it was at after I turned it horizontally.)
This seems to be a problem in one book, but not in others. (The book is "The Swerve" by Stephen Goldblatt.)
Any ideas on what's the problem, or how I can fix it? Or is this just a bug in iBooks?
Deleting and redownloading the iBook fixed it for me.
