Finished Watching Hidden Ads

I'm quitting after finishing the 'Watch 30 Hidden Ads' quest. These ads are so annoying. They only count ads that appear as gold rewards after finishing a stage. But to watch that gold reward ad, I have to watch another ad, and the item reward ads aren't counted as hidden either ㅠㅠ So, I probably watched around 70 ads in total for the 'Watch 30' quest.
