Misleading – Chess? OK! - 3000 chess problems Review

Although the game is fun and the problems are challenging. I reached a point in the game where you can buy to unlock the problems ($9.99!) or continue with ads. I wanted to show some appreciation to the developers so I paid but after paying the ads are still loading between every puzzle. If paying $9.99 doesn’t stop the ads why did I pay at all? Very misleading. If they address this I will edit my review but they have not replied to my feedback requests.
