The scale display alongside the zoom button has never been shown on phones; there isn't enough room.

We have not changed the highlighting of airspaces, it still works fine. It might be that your device is lacking certain drawing commands which are preventing it from drawing certain things on our chart and overlays. Unfortunately we cannot do anything about that, nor tell you the likely scope. There may be other things which are not being shown too. Do you have another device with which you can compare?

New Release is really a step forward.
But I realized two things with my smartphone
a. the scale aside the zoom buttons is not shown
b. the yellow highlighting and fading out of selected airspaces does not work at all.
