Yesterday I was able to watch all my ads and this only happened maybe 3 times, but all I had to do was close the game and click on the button again. Today I only watched 2 ads, so every ad is still available for me but whenever I click on the "free" button it turns to "unavailable" and the video doesn't play. It never does. Is there anything else I can do to try playing the videos besides closing the game and opening again? I already tried that 10 times and it just won't work.
