the last few days I am trying to implement reward video's (admob) in my Unity app. I want to have multiple rewards video's people can watch, with different types of rewards. I feel like I am close (maybe not at all), since I have it working almost correctly. The first time a click on a test ad, it shows the ad, I get the reward and the message that I got the reward. If I then load/watch the second ad, it works, but the reward is not as it should be. I get both rewards. So, I first watch an ad for 100 coins, I get 100 coins, and it works perfectly. Then, I watch the 500 coins ad, but I get 600 coins, and both the messages that I received 100, and 500 coins, although I only 'earned' the 500 coins. It looks like there is a misstake somewhere with both the HandleRewardBasedVideoRewardedAdMob, but I have tried everything I can think of, and I have not found anything similar on the internet. I used small for 100 coins reward, and big for 500 coins. I hope someone can help me out, since it is making me crazy. Thank you for your time!

RewardBasedVideoAd is a singelton object (unlike BannerView and InterstitialAd). In your InitializeAds method you are assigning same object to RequestRewardedVideosmall and rewardBasedAdMobVideobig. You cannot request more than one RewardBasedVideoAd at the time.
You can read more about it here
Because RewardedBasedVideoAd is a singleton, requests to load an ad should be made using a shared instance.
