I created the menu you see on the right side of the screen, it slides out with swipe left.
I then added a hot spot to the 3rd icon from the bottom (mall) and set it as Screen as Overlay, slides up from the bottom and this is the result.
So far all is good, and the overlay stays in place until I click off of it. But on my android phone (Galaxy A5), when I click the Mall icon the overlay just flashes and disappears. It won't stay fixed. Any idea on how to fix this? Doesn't matter if I use SMS link or Invisionapp app, it just flashes and disappears.
