Apps not updating on iPad 3/new (iOS 7)?

Question

iOS

Good day,
There was a problem with the iPad 3, version iOS 7.0.4 - a couple of weeks ago, applications from the App Store stopped updating, later the "update all" button disappeared. When you try to click the "update" button, the application opens .
I tried to free up space, rebooted the iPad, turned on / off updates in the background. Any advice on what else to try? I consider updating to iOS 8 as a last resort :)

Answer 1

re-login to itunes (in settings)?

Answer 2

Open the app's full page in the store, from there the "refresh" button works.
