A Store update (Version 11606.1000.43.0) is rolling out  that includes some good performance improvements to prevent the Store from crashing and using up too much resources on your devices. You should see an overall improvement navigating the Store and visiting app pages.

As per reported earlier only visible notice is that the individual apps have some UI fixes and you can now see the screenshots correctly.
