The main problem with this new icon design is that it doesn't seem to understand / respect the original idea. The original "A" cleverly used a flat design to give the impression of three sticks being piled alternatingly on each other. The "negative space" has the blue background shine through, to give the impression of each stick casting a shadow on the one below.
Like it or not, it is actually a clever design: flat yet 3D. The Blue on White version (old version in this article) doesn't work any longer, because swapping colors removes the shadow logic, but I would still bye it as a means to link the two, yet have them be distinguished products.
But applying a 3D gradient to the "sticks" (whether that is supposed to cut out the shape or give the sticks a 3D shape) just doesn't make any sense. As if who ever did the new one did not understand the original design. Maybe it is time for a new icon area but then the designs should start from the original ruler, pen, brush icon and re-interpret it in whatever new approach is taken, instead of taken an interpretation and just apply some effect to it.
Last but not least - having grown up in East Germany, the App Store icon always reminded me wayyyy too much of the East German Flag:
Good old times ... good old times 😃
