App Store Glitch
Some developers on Twitter have noticed strange happenings when it comes to their apps. It’s believed to be a bug in the App Store Ratings & Reviews system, rather than Apple clearing out old ratings and reviews.
So far it seems like it’s only affecting the iOS App Store and not the Mac App Store.
