I've owned my iPad (4th gen) for a few months and my App Store settings have "automatic downloads" disabled. Never had an issue before, and I always received notifications that I had apps needing updates. This morning, I had 13 apps with updates (all for iOS7 compatibility), but my iPad is on iOS6 so I figured I'd wait to update. I just "woke up" the iPad and now none of the notifications are showing, and my Update page says that all apps are up to date. What could be causing this?
