I have noticed this issue since I updated to version 9. I thought it might be that I had an older iPad and since I would within a few months buy a new one the problem be rectified. Not the case. I have all that I can have of my resources downloaded to my iPad. The issue is my resource will disappear. Examples: I be scrolling as I read then I could scroll no more, sometimes I change screen and when I go back to a previous screen it disappear. The book is still open and it is there because I can tap on the disappearing book and options appear. If I clear the app from memory then reopen it then all appears again. As far as I can tell there is no rhythm or reason when and how it happens. Any help be appreciated. 😀
