Unity ads working nice in the editor but I can't see them on my phone

Hi!

So I integrated Unity ads and when I test it its cool and working. (Because that little box with the close button appears)

But when I use my game on my phone then When it reaches the 3 deaths then it doesn't show ads.

Why?

I've got a game object called "GameController". This is in the start method:

Code (CSharp):

1. if (Advertisement.isSupported) {
2.             Advertisement.allowPrecache = true;
3.             Advertisement.Initialize("MYCODE");
4.         }

And then I've got this in the Update() method:

Code (CSharp):

1. if (TapSpawnerRandom.dieCounter == 3 && Advertisement.isReady()) {
2.             if (!Advertisement.isShowing) {
3.                 Advertisement.Show(null, new ShowOptions {
4.                     pause = true,
5.                     resultCallback = result => {
6.                     }
7.                 });
8.  
9.             }
10.             TapSpawnerRandom.dieCounter = 0;
11.         }

Is there anything I do wrong?

 

And on the UnityAds page I created a new game and I just used that ID what I can see there.

 

Thanks!
