Just joined your forum as I have a problem with missing apps on my ipad2.
I have at least 6 app icons which are missing, in the app store I had the opportunity to update them and they briefly reappeared whilst they were updating and once the update completed they disappeared again.
I have tried rebooting but no joy.
They are available to view in the app store under purchases where it says they are installed but I can't find them anywhere.
Any help would be greatly appreciated, thanks in advance.
