Other Unity ads not working in Android Mobile but in editor it works

Hi
I'm using unity 2020.3.23f1 and I've imported (UnityAds Example App) from Package Manager.
I've changed GameID and other things but still, it's not working in Android.

 

This is what happened...

Code (CSharp):

1. using System;
2. using System.Collections;
3. using UnityEngine.Advertisements;
4. using UnityEngine;
5.  
6. public class UnityAdsManager : MonoBehaviour, IUnityAdsInitializationListener, IUnityAdsLoadListener, IUnityAdsShowListener
7. {
8.     public string GAME_ID = "4807220"; //replace with your gameID from dashboard. note: will be different for each platform.
9.  
10.     private const string BANNER_PLACEMENT = "Banner_Android";
11.     private const string VIDEO_PLACEMENT = "Interstitial_Android";
12.     private const string REWARDED_VIDEO_PLACEMENT = "Rewarded_Android";
13.  
14.     [SerializeField] private BannerPosition bannerPosition = BannerPosition.BOTTOM_CENTER;
15.  
16.     private bool testMode = true;
17.     private bool showBanner = false;
18.  
19.     //utility wrappers for debuglog
20.     public delegate void DebugEvent(string msg);
21.     public static event DebugEvent OnDebugLog;
22.  
23.     public void Initialize()
24.     {
25.         if (Advertisement.isSupported)
26.         {
27.             DebugLog(Application.platform + " supported by Advertisement");
28.         }
29.         Advertisement.Initialize(GAME_ID, testMode, this);
30.     }
31.  
32.     public void ToggleBanner()
33.     {
34.         showBanner = !showBanner;
35.  
36.         if (showBanner)
37.         {
38.             Advertisement.Banner.SetPosition(bannerPosition);
39.             Advertisement.Banner.Show(BANNER_PLACEMENT);
40.         }
41.         else
42.         {
43.             Advertisement.Banner.Hide(false);
44.         }
45.     }
46.  
47.     public void LoadRewardedAd()
48.     {
49.         Advertisement.Load(REWARDED_VIDEO_PLACEMENT, this);
50.     }
51.  
52.     public void ShowRewardedAd()
53.     {
54.         Advertisement.Show(REWARDED_VIDEO_PLACEMENT, this);
55.     }
56.  
57.     public void LoadNonRewardedAd()
58.     {
59.         Advertisement.Load(VIDEO_PLACEMENT, this);
60.     }
61.  
62.     public void ShowNonRewardedAd()
63.     {
64.         Advertisement.Show(VIDEO_PLACEMENT, this);
65.     }
66.  
67.     #region Interface Implementations
68.     public void OnInitializationComplete()
69.     {
70.         DebugLog("Init Success");
71.     }
72.  
73.     public void OnInitializationFailed(UnityAdsInitializationError error, string message)
74.     {
75.         DebugLog($"Init Failed: [{error}]: {message}");
76.     }
77.  
78.     public void OnUnityAdsAdLoaded(string placementId)
79.     {
80.         DebugLog($"Load Success: {placementId}");
81.     }
82.  
83.     public void OnUnityAdsFailedToLoad(string placementId, UnityAdsLoadError error, string message)
84.     {
85.         DebugLog($"Load Failed: [{error}:{placementId}] {message}");
86.     }
87.  
88.     public void OnUnityAdsShowFailure(string placementId, UnityAdsShowError error, string message)
89.     {
90.         DebugLog($"OnUnityAdsShowFailure: [{error}]: {message}");
91.     }
92.  
93.     public void OnUnityAdsShowStart(string placementId)
94.     {
95.         DebugLog($"OnUnityAdsShowStart: {placementId}");
96.     }
97.  
98.     public void OnUnityAdsShowClick(string placementId)
99.     {
100.         DebugLog($"OnUnityAdsShowClick: {placementId}");
101.     }
102.  
103.     public void OnUnityAdsShowComplete(string placementId, UnityAdsShowCompletionState showCompletionState)
104.     {
105.         DebugLog($"OnUnityAdsShowComplete: [{showCompletionState}]: {placementId}");
106.     }
107.     #endregion
108.  
109.     public void OnGameIDFieldChanged(string newInput)
110.     {
111.         GAME_ID = newInput;
112.     }
113.  
114.     public void ToggleTestMode(bool isOn)
115.     {
116.         testMode = isOn;
117.     }
118.  
119.     //wrapper around debug.log to allow broadcasting log strings to the UI
120.     void DebugLog(string msg)
121.     {
122.         OnDebugLog?.Invoke(msg);
123.         Debug.Log(msg);
124.     }
125. }
126.  

and this is the codes...
