Ads showing in editor but not on android device

Hi , I have been trying to implement ads in my game since a while.
They do work great in editor and Unity shows the test ads.Unfortunately , on any mobile device , it doesn't show either test ads nor real ads.
Things I tried :
-Forcing real ads in Unity dashboard
-Initializing in Update()
-Re-importing Unity ads asset
-Disabling and enabling ads
-Made sure am using the right game ID and set the test mode on false ("1235678" , false)
-Tried different codes , all worked in Editor but none on any android device
-Made sure I included advertisement in the script
Can someone give me a clue where I'm going wrong?

 

Here is the code , I tried to put the Initalize both in Start () and Update().
Keep in mind the test ads do work fine in the editor.

Code (CSharp):

1. public class adsManager : MonoBehaviour
2. {
3.     playerStats pSt;
4.     public GameObject rewardPanel;
5.     public Text rewardText;
6.     public Text buttonText;
7.     public shorthandManager shortener;
8.  
9.     void Start()
10.     {
11.  
12.         pSt = GameObject.Find("Player").GetComponent<playerStats>();
13.      
14.  
15.     }
16.  
17.     void Update()
18.     {
19.         Advertisement.Initialize("MYGAMEID", false);
20.         shortener.checkVal((pSt.goldCoins * 0.25f), buttonText);
21.         Advertisement.Banner.Load("banner");
22.         showBanner();
23.  
24.     }
25.  
26.     void showBanner()
27.     {
28.         Advertisement.Banner.Show("banner");
29.     }
30.  
31.     public void goldAd()
32.     {
33.         if (Advertisement.IsReady("rewardedVideo"))
34.         {
35.             var showOptions = new ShowOptions();
36.             showOptions.resultCallback += ResultCallback;
37.  
38.             Advertisement.Show("rewardedVideo", showOptions);
39.         }
40.     }
41.  
42.     private void ResultCallback(ShowResult result)
43.     {
44.         if (result == ShowResult.Finished)
45.         {
46.             rewardPanel.SetActive(true);
47.             pSt.goldCoins += (pSt.goldCoins * 0.25f);
48.             rewardText.text = "CONGRATULATIONS! YOU GOT  " +(pSt.goldCoins * 0.25f) + "  COINS!";
49.         }
50.         else
51.         {
52.             rewardPanel.SetActive(true);
53.             rewardText.text = "YOU DID NOT FINISH WATCHING THE VIDEO.";
54.         }
55.     }
56.  
57. }

 

I have the same problem. Have you been able to solve it?

 

I found this now I try to see if it works

@Zaine7673,

Banners are currently only available in the 3.0 version of the Ads SDK, which you can download from the Asset Store:
https://assetstore.unity.com/packages/add-ons/services/unity-monetization-3-0-66123

If you were using the Services window, you will have to disable the built-in ads extension in the Advanced Settings.

 

I wouldn’t put the initialise in the update.

Needs only be called once.

So put it in Start().
