Yes and Apple acknowledges the issue. The App Store shows you have updates, but when going to update page it is blank. You need to go to the purchased page and scroll through all you apps and look for those that say "update" then update it. A hassle to be sure. The apple folks informed me that it is an iTunes issue and will be resolved soon. This issue has been going on for a week or so (July 25), so "soon" means......?
