Unity ads invalid configuration request for gameid

Hi

I'm trying to integrate and test a simple banner ad on my game. I got 2 errors:
- Invalid configuration request for gameId
- The remote server returned an error: (404) Not Found.

Code (CSharp):

1. public class BannerDisplay : MonoBehaviour
2. {
3.     string myGameIdAndroid;
4.     bool testMode;
5.     string myBannerPlacement;
6.  
7.     void Start()
8.     {
9.         myGameIdAndroid = GameManager.instance.pubMyGameIdAndroid;
10.         testMode = GameManager.instance.pubTestMode;
11.         myBannerPlacement = GameManager.instance.pubMyBannerPlacement;
12.  
13.         Advertisement.Initialize(myGameIdAndroid, testMode);
14.         StartCoroutine(ShowBannerWhenReady());
15.     }
16.  
17.     IEnumerator ShowBannerWhenReady()
18.     {
19.         while (!Advertisement.IsReady(myBannerPlacement))
20.         {
21.             yield return new WaitForSeconds(0.5f);
22.         }
23.  
24.         Advertisement.Banner.Show(myBannerPlacement);
25.     }
26. }

I wrote the ID correctly and the code worked in another project without problem.

I have been looking for a solution in the forum and found that IDs are working 12 hours after you activate ads. I did it yesterday so IDs should be valid right now. I am missing something?

Unity version: 2020.3.8f1
Ads package: 3.7.5

Thanks in advance

 

Thank you for your response.

The Game ID is not working yet so I've just created a support ticket.
