Why my ads is not visible on final build just in editor?

I have some ads on my game like reward video and interstitial video Reward video needs to play when i pres the +20k money button and interstitial when you select a car. In editor everything works perfect but in build nothing work I tried all methods that i find on the internet but is the same problem.

interstitial ad :

     public string mySurfacingId = "Interstitial";
     string gameId = "4****9";
     bool testMode = false;
 
     void Start()
     {
         // Initialize the Ads service:
         Advertisement.Initialize(gameId);
     }
 
     public void ShowInterstitialAd()
     {
         // Check if UnityAds ready before calling Show method:
         if (Advertisement.IsReady())
         {
             Advertisement.Show(mySurfacingId);
             // Replace mySurfacingId with the ID of the placements you wish to display as shown in your Unity Dashboard.
         }
         else
         {
             Debug.Log("Interstitial ad not ready at the moment! Please try again later!");
         }
     }

video reward :

 private string gameId = "4****9";
 
 
     Button myButton;
     public string mySurfacingId = "rewardedVideo";
     public MoneyMNG Money;
     public bool testMode;
     void Start()
     {
         myButton = GetComponent<Button>();
         Advertisement.Initialize(gameId,testMode);
 
         // Set interactivity to be dependent on the Ad Unit or legacy Placement’s status:
         myButton.interactable = Advertisement.IsReady(mySurfacingId);
 
         // Map the ShowRewardedVideo function to the button’s click listener:
         if (myButton) myButton.onClick.AddListener(ShowRewardedVideo);
 
         // Initialize the Ads listener and service:
         Advertisement.AddListener(this);
         
     }
 
     // Implement a function for showing a rewarded video ad:
    public void ShowRewardedVideo()
     {
         // Check if UnityAds ready before calling Show method:
         if (Advertisement.IsReady(mySurfacingId))
         {
             Advertisement.Show(mySurfacingId);
         }
     }
 
     // Implement IUnityAdsListener interface methods:
     public void OnUnityAdsReady(string surfacingId)
     {
         // If the ready Ad Unit or legacy Placement is rewarded, activate the button: 
         if (surfacingId == mySurfacingId)
         {
             myButton.interactable = true;
         }
     }
 
     public void OnUnityAdsDidFinish(string surfacingId, ShowResult showResult)
     {
         // Define conditional logic for each ad completion status:
         if (showResult == ShowResult.Finished)
         {
             // Reward the user for watching the ad to completion.
             PlayerPrefs.SetInt("Money", PlayerPrefs.GetInt("Money") + 20000);
             Money.Update2();
             Debug.Log("Rewarded");
         }
         else if (showResult == ShowResult.Skipped)
         {
             // Do not reward the user for skipping the ad.
            
         }
         else if (showResult == ShowResult.Failed)
         {
             
         }
     }
 
     public void OnUnityAdsDidError(string message)
     {
         // Log the error.
     }
 
     public void OnUnityAdsDidStart(string surfacingId)
     {
         // Optional actions to take when the end-users triggers an ad.
     }
