Sep 26, 2014 Since the App Store has no refresh button, I used to force close the app, and reopen it to check for new updates. There’s an even easier way to refresh the App Store. I’m not sure if it was purposely done, or if it’s a bug, or what. All I know is that this refresh trick works on iOS 8 and newer versions of the software, but it doesn’t. I had that issue with the 2.0.1 update as well. What finally worked for me (see this Apple Support Discussion) was downloading Pacifist and using it to install the update that I downloaded manually from the Apple Support site here.All you have to do is choose 'Open Package' in Pacifist, select the Pro Video update disk image, and install the top-level item ('Contents of dmg name.dmg').
