Fun but how do I report a mistake?

I really do like the game, because I want to challenge myself without an opponent. I like the adjustable difficulty based on performance. My only drawback is that no option exists to report a mistake. One question asks which Errol Flynn film does NOT also star Olivia DeHavilland. All of the films listed as answers star both performers and in the so-called answer "They Died with Their Boots On", Olivia plays Errols wife!
