I ran into this problem about a week ago where I can’t update my apps, whether they be paid or free ones. I also can’t install new ones. Now, that is definitely unacceptable. I had such fun with Sketch Pro and had made a couple of artworks (see below) during my free time, and I wanted to explore other graphics apps too.
At first, I thought there might be a problem with my iPad but when the same thing happened to my iPhone too, no doubt, it must have something to do with my itunes account. A little digging revealed that I have some problem with my billing card. At least that’s what iTunes was telling me.
I can’t seem to fix the problem in the ipad or iphone, so I finally signed in using the itunes app in my PC and accessed my account data.
I went to ‘Purchase History’ and clicked on the ‘See All’ link. There I saw that my last purchased app, the Sketch Pro, was not paid, although I’ve downloaded and had used it. ITunes said it was denied by my card; or there was a problem with my card, or something to that effect.
My account page had some red text in there that suggested I re-enter the last digits of my card. So, seeing that there’s nothing wrong with re-typing what I’ve already typed before, (and praying that this be not some hacker’s replica of the iTunes legitimate program) I did.
ITunes then reflected that the last app was now paid. Then I went back to my iPad and checked it out. Sure enough I was able to update my apps, both paid and free.
I guess that it must either be a glitch in iTunes’ system (which was announced by this guy’s article here), or that my card’s bank happened to go offline during my purchase.
