Just started for me, but the game crashes after every ad. This popped up.

I was unable to clear my cache because that option went away after taking the screenshot.
Also, and more importantly, no rewards are given for watching the ad to completion as the game constantly crashes when the ad is over.
You might want to make this a priority as we are going to stop watching ads and you won't get paid.
