Cant update apps from AppStore with iOS 8
After I upgrade my iPad mini retina (A1490) to iOS 8, I found all my apps cannot update in AppStore.
Neither clicking on the 'update' button for each app nor 'update all' in AppStore will work, and no progress was made, just the round indicator circling forever.
Has any one met this problem and know what is going on?
iPad, iOS 8
