Apple App Store not showing correct icon in iOS 7

I've updated one of my apps to support both iOS6 and iOS7. After the update was approved, the icon for the app in search results is incorrect on iOS7.

As you can see, the icon is correct on the app page, but not correct in the search results page (you can tell by the rounded corners). It is showing the iOS6 icon in the search results.

I setup the icons for the projects with the new method that uses the Images.xcassets folder. In iTunesConnect, I uploaded the new icon, and the iTunesArtwork and iTunesArtwork@2x files are both the correct versions.

I'm fairly convinced this is an issue on Apple's end. Here is a thread on another website about the same issue: iOS7 App store search icons. Btw, if you check various apps in the App Store, you can see that a lot of them have this common problem, the icon displayed in search results is the incorrect/iOS6 version.

Anybody know what the deal is? This is so annoying.

If you were looking for an answer to this problem, this isn't the answer you were looking for. I feel that it is too late in the game for Apple to do anything about this issue, since at this point nobody cares about iOS6. Therefore, the best course of action is to just make all icons for iOS7, meaning if you have a border in your icon, make the roundness of the border match iOS7 for all sizes. This will result in the icon looking slightly weird on an iOS6 device, but at this point that is an extremely minor issue.
