I just updated my iPad this morning and while view in full page mode (portrait and landscape) I get a white screen. Shifting out of full screen allows me to read for about 10 minutes, then it locks up.
After closing the app and reopening, I get the white screen. Sometimes I can get out of the full screen and then it resets the last read to where I was before Updating to iOS.
Any ideas or suggestions? Hopefully not involving deleting the app (I’d hate to reload all theses books!).
