My game opens perfectly fine, and runs well, but I note that rather than filling the screen, there's a black space at the bottom. Now I'm using Scale Outer, so this should work fine. I've also used letterbox and received the same result. I'm not understanding.
Now! If I ever switch out of the game, then switch back over to it, the game pops to full screen mode, and the small black box at the bottom disappears.
I've created another mobile app at the same time, and that one isn't showing the same problem. The only difference between the 2 is that one has ads and the other doesn't.
Could it be that the app is preparing the space for the advert but not resizing the screen?
