Hello, today I noticed that on my iPad, I can't review any of the apps I got through Redemption Codes given to me by the developers. The App Store on the iPad shows that I have Installed the application, but when I try to review it, a message pops up saying: "You do not own this item... etc.". This must be a recent problem as in the past I was able to review all apps I have installed, without any problems. Is anyone else experiencing this problem?
