I discovered that the apps are actually there on the screen, but you can't see them, as reported. Try clicking where the app should be on the blank page. I found that the app detail opens up on a new screen. Strange.
Mine is now working, and other people have reported that it's working for them - is your's now ok ? If not then try logging out of your account on the iPad by tapping on your id in Settings > Store and then log back in and see if they then show.
