title: Can't trigger events in unity 2018
body: <p>Hi i am trying to implement admob rewarded video for my game. I have imported admob sdk and implemented all required methods. The ad is loading and showing correctly but the problem is that i have added events in my code to detect when the ad is finished. Unfortunately my events are not called.<a href="https://i.stack.imgur.com/INDw6.png" rel="nofollow noreferrer">registered event listeners</a> <a href="https://i.stack.imgur.com/aH5oo.png" rel="nofollow noreferrer">this is where i request and show rewarded video</a></p>
