We could not complete your purchase cancelled
I am receiving the following message when trying to update apps I have already purchased through the App Store: "We could not complete your purchase cancelled". The App Store is showing that I have 4 apps to update, but I am not able to update any of them. I have tried both the Update All and to update them individually with the same results. From the posts this seems as if this issue has happened in the past on the App Store, but I have never experienced it before. The solution appears to be that it just begins working on its own eventually. This issue has been occurring for over a week now. I have not seen any recent posts on this issue, so thought I would post it again.
