I downloaded a number of books, and I have the airplane icon on the books.
However, when I did not have internet access, and tried to open the books, the Unable to load book dialog appeared. I tried this for several books, and none of them worked other than my NASB.
The difference was that after downloading I had opened the NASB. I did not try to open the other books until I was offline.
I went online, and opened one of the books, The Complete Works of Miles Stanford. Then I went offline and tried that book again. This time it worked.
Anyway, it appears there is a bug which will not allow you to read a downloaded book unless you have first opened the book while online.
Has anyone else seen this kind of behavior?
This post is mostly for reporting so it can be fixed in a later update.
