App Store Not Working or Showing Updates? How to Refresh the App Stores
Need to refresh the App Store or iTunes Store? Hit Command+R at any screen in the iTunes, iOS, or Mac App Store, and the page will reload with whatever new data awaits, whether it’s a revised Top Charts listing or just to see the latest Featured apps. You can refresh any screen in any of the Apple iTunes or App Stores with this method,
Reloading an App Store page is also an easy way to resolve quite a few common issues, like when the App Store claims to be inaccessible, new app updates aren’t displaying, or when recently purchased items are missing from the Purchased list. If something is still not appearing in the purchases list after a refresh, it could be hidden, here’s how to unhide it.
Note this is for the desktop versions of the App Store, on the iOS side you can typically just quit and relaunch iTunes or App Store to resolve any problems. If that doesn’t work, you may need to manually force quit the App Store itself or even reboot the device to fix stalled downloads and force updates to the page.
