iBooks keep disappearing from iPad
Why does iBooks on iPad keep deleting my iBooks and PDF's?
I have the latest version of iOS and iPad Model A1458. I do not sync my iBooks. I manually drop them into iBooks from iTunes.
This is happening more and more frequently. It deleted all of my books and PDF's but a few. Originally I had sorted them all in various categories and one day they just weren't there. There were so many of them I waited to reload them. After reloading them, they disappeared again. And again. This is at least the 4th time.
It may happen when I plug into my computer.
Any help would be greatly appreciated.
If there is a better app to that reads both epub and PDF whereby I can sort into my own chosen categories that would be an acceptable solution as well.
Kindle does not seem to be affected.
