First of all, thanks you all this forum that I was able to integrate the videos reward heyzap in my application. However I have a recurring problem. I have an admob banner and a reward corner button on the same page at the end of the game. Everything is displayed correctly but when I click on the video reward, the video starts without problem and the reward too but when the game returns the admob banner disappeared and never reappears even after several games. I am obliged to close the game and to restart it so that it reappears. Do you have an idea ? For information, I don't use heyzap mediation.
Maybe you could check for the reafresh rate in the admob site in your banner options, not sure but try.
