To update this application, sign in to the account you used to purchase it.
Some of my apps have available updates but this is the response I get when I try to update: "To update this application, sign in to the account you used to purchase it." I am bewildered since I only have one account that I am already signed into. How do I get the apps to update? What account is the app store talking about?
