Several Apps on the App Store App site have been changed and now only show a watch face. They no longer show the App screen. Wonder if this means this Apps have had last minute redesigns or are they receiving special attention?
You have to wait for the animation to download. They start on the watch face and then animate to show how they work. Although I noticed sometimes it seems to glitch out and not show the animation? For instance, I just made an edit to this and switched tabs back and it started playing the AA animation.
They were not animated previously. It looks like Apple is in the process of adding animation at this time.
I could have sworn that when I visited this site a couple weeks ago they had animations.
