Can't see all tiles – Mahjong 2 Review

I love the game - challenging! It crashes too often and the right side of the tiles are hidden. I've played through and am now on the Inca tile. When it opens there are tiles not visible on the bottom and today there is an ad on the top which covers the top tiles. I'm acing to tap and tile and either move up or down to match it with another tile. When you touch the screen to move it, you've lost the first tile. Frustrating, to be honest!!!
