Great game until this – Line Physics: Drawing Puzzle Review

I absolutely love this game and it is great but when I touch the hint button it says “there is no rewarded video.”but that not the only button that does it. All the buttons that let you watch an ad do that no matter what even when I’m online. Can you please fix this?
