Unity Banner is not showing - unity3d

Question

My Banner Ad does show in test mode but without testmode not.
I used a code template from the unity website.
I also asked the unity ads support but they couldn't find the error.
they send me a video of my application,and in this video the banner ad worked.
Here is my code:
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Advertisements;
public class newadsystem : MonoBehaviour
{
// For the purpose of this example, these buttons are for functionality testing:
[SerializeField] Button _loadBannerButton;
[SerializeField] Button _showBannerButton;
[SerializeField] Button _hideBannerButton;
[SerializeField] BannerPosition _bannerPosition = BannerPosition.BOTTOM_CENTER;
[SerializeField] public string _androidAdUnitId = "Banner_Android";
[SerializeField] string _iOsAdUnitId = "Banner_iOS";
public string _adUnitId = "Banner_Android";
void Start()
{
Advertisement.Initialize("4395157",false,true);
// Disable the button until an ad is ready to show:
_showBannerButton.interactable = true;
_hideBannerButton.interactable = true;
// Set the banner position:
Advertisement.Banner.SetPosition(_bannerPosition);
// Configure the Load Banner button to call the LoadBanner() method when clicked:
_loadBannerButton.onClick.AddListener(LoadBanner);
_loadBannerButton.interactable = true;
}
// Implement a method to call when the Load Banner button is clicked:
public void LoadBanner()
{
// Set up options to notify the SDK of load events:
BannerLoadOptions options = new BannerLoadOptions
{
loadCallback = OnBannerLoaded,
errorCallback = OnBannerError
};
// Load the Ad Unit with banner content:
Advertisement.Initialize("4395157", false, true);
Advertisement.Banner.Load(_adUnitId, options);
Advertisement.Initialize("4395157", false, true);
}
// Implement code to execute when the loadCallback event triggers:
void OnBannerLoaded()
{
Debug.Log("Banner loaded");
// Configure the Show Banner button to call the ShowBannerAd() method when clicked:
_showBannerButton.onClick.AddListener(ShowBannerAd);
// Configure the Hide Banner button to call the HideBannerAd() method when clicked:
_hideBannerButton.onClick.AddListener(HideBannerAd);
// Enable both buttons:
_showBannerButton.interactable = true;
_hideBannerButton.interactable = true;
}
// Implement code to execute when the load errorCallback event triggers:
void OnBannerError(string message)
{
Debug.Log($"Banner Error: {message}");
// Optionally execute additional code, such as attempting to load another ad.
}
// Implement a method to call when the Show Banner button is clicked:
void ShowBannerAd()
{
// Set up options to notify the SDK of show events:
BannerOptions options = new BannerOptions
{
clickCallback = OnBannerClicked,
hideCallback = OnBannerHidden,
showCallback = OnBannerShown
};
// Show the loaded Banner Ad Unit:
Advertisement.Initialize("4395157", false, true);
Advertisement.Banner.Show(_adUnitId, options);
}
// Implement a method to call when the Hide Banner button is clicked:
void HideBannerAd()
{
// Hide the banner:
Advertisement.Banner.Hide();
}
void OnBannerClicked()
{
Debug.Log("Banner Clicked!");
}
void OnBannerShown()
{
Debug.Log("Banner Shown!");
}
void OnBannerHidden()
{
Debug.Log("Banner Hidden");
}
void OnDestroy()
{
// Clean up the listeners:
_loadBannerButton.onClick.RemoveAllListeners();
_showBannerButton.onClick.RemoveAllListeners();
_hideBannerButton.onClick.RemoveAllListeners();
}
}
I looked into the android device log and there was: "Unity : Banner Error: UnityAds is not initialized."
but i call several times the initialize function.
PS: i am not very good at english.

Have a look at Start (), your code:
Advertisement.Initialize("4395157",false,true);
// Disable the button until an ad is ready to show:
_showBannerButton.interactable = true;
_hideBannerButton.interactable = true;
And then at OnBannerLoaded ()
// Enable both buttons:
_showBannerButton.interactable = true;
_hideBannerButton.interactable = true;
But those button are already interactable = true.
Maybe you need to change Start () like this:
Advertisement.Initialize("4395157",false,true);
// Disable the button until an ad is ready to show:
_showBannerButton.interactable = false;
_hideBannerButton.interactable = false;
Update 1
Try to change your code the following way:
void Start()
{
_showBannerButton.interactable = false;
_hideBannerButton.interactable = false;
Advertisement.Initialize("4395157",false,true);
_loadBannerButton.onClick.AddListener(LoadBanner);
_showBannerButton.onClick.AddListener(ShowBannerAd);
_hideBannerButton.onClick.AddListener(HideBannerAd);
_loadBannerButton.interactable = true;
}
public void LoadBanner()
{
BannerLoadOptions options = new BannerLoadOptions
{
loadCallback = OnBannerLoaded,
errorCallback = OnBannerError
};
if (Advertisement.isInitialized) {
Advertisement.Banner.Load(_adUnitId, options);
} else Debug.LogWarning ("Adverisement not initialized! Try again later");
}
void OnBannerLoaded()
{
Debug.Log("Banner loaded");
BannerOptions options = new BannerOptions
{
clickCallback = OnBannerClicked,
hideCallback = OnBannerHidden,
showCallback = OnBannerShown
};
Advertisement.Banner.SetPosition(_bannerPosition);
_showBannerButton.interactable = true;
_hideBannerButton.interactable = true;
}
void ShowBannerAd()
{
Advertisement.Banner.Show(_adUnitId, options);
}
