So, I am trying to update a few of my apps off the app store, but when when I try to update the apps, I get this message: "This discounted price is only available to customers who own a previous version of this item. To purchase this item at full price, click Buy". As you can see, my problem is that I already own the apps that it is trying to get me to purchase again. I called Apple, and they couldn't help me at all. What do you guys think? All help is greatly appreciated.
