Bug Test ads works perfectly but when I try to put real ads nothing appears

I made a mobile game in which i am able to display the test ads without any problem or difficulty.

But when I tried to show real ads nothing appeared. I made sure that the test ads were disabled both on the dashboard, in the project settings and in the script doing the initialization.
The ids are correct and the project is correctly tied to unity ads, and is indeed monetized.
I tried it after building the app into an apk file and using it on my phone and after I tried it by making an internal test on google play console.

I am writing here because i don't see what to do to solve the problem and found nothing on the internet.

here is the code I use to initialize the ads:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Advertisements;
3.  
4. public class AdsInitializer : MonoBehaviour, IUnityAdsInitializationListener
5. {
6.     [SerializeField] string _androidGameId = "5267275";
7.     [SerializeField] string _iOSGameId = "5267274";
8.     [SerializeField] bool _testMode = false;
9.     private string _gameId;
10.  
11.     void Awake()
12.     {
13.         InitializeAds();
14.     }
15.  
16.     public void InitializeAds()
17.     {
18.        
19.         _gameId = _androidGameId;
20.         Advertisement.Initialize(_gameId, _testMode, this);
21.     }
22.  
23.     public void OnInitializationComplete()
24.     {
25.         Debug.Log("Unity Ads initialization complete.");
26.     }
27.  
28.     public void OnInitializationFailed(UnityAdsInitializationError error, string message)
29.     {
30.         Debug.Log($"Unity Ads Initialization Failed: {error.ToString()} - {message}");
31.     }
32. }

Then this is the code i use to display the ads

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.Advertisements;
4.  
5.  
6. public class BannerAd : MonoBehaviour
7. {
8.  
9.     [SerializeField] BannerPosition _bannerPosition = BannerPosition.BOTTOM_CENTER;
10.  
11.     [SerializeField] string _androidAdUnitId = "Banner_Android";
12.     [SerializeField] string _iOSAdUnitId = "Banner_iOS";
13.     string _adUnitId = null;
14.  
15.     void Start()
16.     {
17.        
18.         _adUnitId = _androidAdUnitId;
19.         Advertisement.Banner.SetPosition(_bannerPosition);
20.  
21.         LoadBanner();
22.     }
23.     void Update()
24.     {
25.         ShowBannerAd();
26.     }
27.  
28.     public void LoadBanner()
29.     {
30.         BannerLoadOptions options = new BannerLoadOptions
31.         {
32.             loadCallback = OnBannerLoaded,
33.             errorCallback = OnBannerError
34.         };
35.  
36.         Advertisement.Banner.Load(_adUnitId, options);
37.     }
38.  
39.     void OnBannerLoaded()
40.     {
41.         Debug.Log("Banner loaded");
42.         ShowBannerAd();
43.     }
44.  
45.     void OnBannerError(string message)
46.     {
47.         Debug.Log($"Banner Error: {message}");
48.     }
49.  
50.     void ShowBannerAd()
51.     {
52.         BannerOptions options = new BannerOptions
53.         {
54.             clickCallback = OnBannerClicked,
55.             hideCallback = OnBannerHidden,
56.             showCallback = OnBannerShown
57.         };
58.  
59.         Advertisement.Banner.Show(_adUnitId, options);
60.     }
61.  
62.     void HideBannerAd()
63.     {
64.         Advertisement.Banner.Hide();
65.     }
66.  
67.  
68.  
69.     void OnBannerClicked() { }
70.     void OnBannerShown() { }
71.     void OnBannerHidden() { }
72.  
73.     void OnDestroy() { }
74. }

 

this is a screeshot of the app-ads-txt-support.

I am not sure I understand what it means by the root of the developer's website. For example, I want to put my game on the app store, for that i am using the google play console. What link do I put, is it just the one of the app when it is released for the public?

 

Sorry again.

I made a small site to put in here:

since the url is not accepted it appears i am missing on some requirements.
Do you know why my link is not accepted, and could you tell me what kind of links are accepted by unity ads?

 

Sorry about that, now here is what it says

 

Is it not a problem that i am using a website creation tools?
because the root does not link to my website and does not belong to me.
