Big ad reward problem

Hi, i released my game and i noticed that when i click on the button fast enough before the ad appears the player gets the reward more than once!

Code (CSharp):

1.     public void ShowAd30secForCoins()
2.     {
3.         if (Advertisement.IsReady())
4.         {
5.             Advertisement.Show("rewardedVideo", new ShowOptions() { resultCallback = HandleResult30ForCoin });
6.         }
7.     }
8.  
9.     public void HandleResult30(ShowResult result)
10.     {
11.         switch (result)
12.         {
13.             case ShowResult.Finished:
14.                 Spins += 3;
15.                
16.                 //  Debug.Log("Win30");
17.                 break;
18.             case ShowResult.Skipped:
19.                 //  Debug.Log("Skip");
20.                 break;
21.             case ShowResult.Failed:
22.                 //  Debug.Log("Fail");
23.                 break;
24.         }
25.     }

 

Why don't you do something like?

Code (CSharp):

1. bool rewarded;
2.  
3. public void ShowAd30secForCoins()
4.     {
5.         if (Advertisement.IsReady())
6.         {
7.             rewarded = false;
8.             Advertisement.Show("rewardedVideo", new ShowOptions() { resultCallback = HandleResult30ForCoin });
9.         }
10.     }
11.     public void HandleResult30(ShowResult result)
12.     {
13.         switch (result)
14.         {
15.             case ShowResult.Finished:
16.                 if(!rewarded)
17.                     Spins += 3;
18.                 rewarded = true;
19.              
20.                 //  Debug.Log("Win30");
21.                 break;
22.             case ShowResult.Skipped:
23.                 //  Debug.Log("Skip");
24.                 break;
25.             case ShowResult.Failed:
26.                 //  Debug.Log("Fail");
27.                 break;
28.         }
29.     }

Might not be the prettiest fix, but should work

 

Nope, That's not working.
It's like doing the same.
Maybe i can make an Invoke function that after a second it can be pressed again.

Edit: Well, the invoke with your solution work.
A bit lame but that's enough lol.
Thanks
