How to Implement the Show Listener's OnUnityAdsShowComplete callback method

Hi, the code tells me

Code (CSharp):

1. // Implement the Show Listener's OnUnityAdsShowComplete callback method to determine if the user gets a reward:
2.     public void OnUnityAdsShowComplete(string adUnitId, UnityAdsShowCompletionState showCompletionState)
3.     {
4.         if (adUnitId.Equals(_adUnitId) && showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
5.         {
6.             Debug.Log("Unity Ads Rewarded Ad Completed");
7.             // Grant a reward.
8.            
9.            
10.          
11.             // Load another ad:
12.             Advertisement.Load(_adUnitId, this);
13.         }
14.     }

So question is how to /Implement the Show Listener's OnUnityAdsShowComplete callback method to determine if the user gets a reward?

 

@Esteban_Unity_COL is that guide updated for the new dialog Unity pops up the first time the game plays an ad? we had our code working fine until this new thing appeared and now the first ad always gets a
OnUnityAdsDidError event triggered ... are these both things correlated?

 

Thanks we already did.
