Mysterious Society : Crime scene hidden object features game

Everything was fine until level four. Couldn’t find matchstick. Broke down and purchased clue package. Showed it to be in an area located behind a large four indicating the level you’re on. Broke down and bought ad free package hoping this would clear up screen enough to let me work past the problem. Not only did that not work but I still have a top banner full of ads! I give up and assume my $6.98 is gone too.
