Since the recent update I have screen size issues on my iPad. For example, if I want to buy alloy barrels I have to close the game to use them as everything on the screen is pushed up high and I can no longer access the “X” close button. Same problem in promoting troops. Is there a fix please. Or can anyone tell me how to register my chagrin with the devs? Many thanks
