Recently several of the video advertisements have not been ads but surveys. Please stop placing those as our ads. They fit nicely as a way to earn free donuts in the shop. After waiting an hour for an ad to be available it is very frustrating to open it just to find that you don't qualify for the reward. If we sit through their sales pitch we should have our time shortened regardless of weather we are their target demographic or not.
Also a refresh button in the ad would be great since they frequently don't load right and there's no way to fix this besides abandoning the ad.
