Ads not working in fresh project

I'm using Unity 2018.3.9f1 (Personal) to create a simple test project to test how Unity Ads work.
I do the following steps:

1) Switch platform to Android from Build Settings
2) Go into Services and enable ADS
3) Enable test mode within ADS tab
4) Enable built-in Ads extension
5) Create a super simple script to start the default rewardedVideo once it is ready

but nothing happens. When game is run in editor I get the following log in console:

Code (CSharp):

1. UnityAdsEditor: Initialize(XXXXXXX, True);
2. UnityEditor.Advertisements.UnityAdsEditor:EditorOnLoad()

I can see that XXXXXXX is the correct game id, that matches the one in dashboard. So it seems to initialize the ads successfully.

Here is the simple script that tries to show an ad:

Code (CSharp):

1. using System.Collections;
2. using UnityEngine;
3. using UnityEngine.Advertisements;
4.  
5. public class AdManager : MonoBehaviour {
6.  
7.     void Start() {
8.         StartCoroutine(ShowAdWhenReady());
9.     }
10.  
11.     IEnumerator ShowAdWhenReady() {
12.         Debug.Log("In coroutine");
13.         while (!Advertisement.IsReady("rewardedVideo")) {
14.             yield return null;
15.         }
16.         var options = new ShowOptions { resultCallback = HandleShowResult };
17.         Advertisement.Show("rewardedVideo", options);
18.     }
19.  
20.     private void HandleShowResult(ShowResult result) {
21.         switch (result) {
22.             case ShowResult.Finished:
23.                 Debug.Log("The ad was successfully shown.");
24.                 //
25.                 // YOUR CODE TO REWARD THE GAMER
26.                 // Give coins etc.
27.                 break;
28.             case ShowResult.Skipped:
29.                 Debug.Log("The ad was skipped before reaching the end.");
30.                 break;
31.             case ShowResult.Failed:
32.                 Debug.LogError("The ad failed to be shown.");
33.                 break;
34.         }
35.     }
36. }
37.  

I can see coroutine start, but it never exits the while loop, meaning that the

!Advertisement.IsReady("rewardedVideo")

is always true. In other words ad is never ready.

I have created several fresh projects and tried all kinds of things, like creating an ad and not using one of the pre-created ones. I have tried setting Enable built-in Ads extension to false and using the SDK from Asset Store. I have tried manually initializing the Advertisements with no luck. It drives me crazy how simple every tutorial makes it look, yet someone with extensive programming and unity knowledge can't get this to work.

Any help is appreciated!

 

Yeah that was exactly how I did it, disabled everything in one before trying the other. Was never mixing them together. But Package Manager upgrade of Ads to 3.0.3 is something I had not yet done, and that seemed to have fixed it Such a simple step, but not mentioned anywhere. Hopefully this post will help others like me in the future. Thank you!

 

@DenisasK i upgraded to ads to 3.2.0 but got a new problem

private void HandleAdResult(ShowResult result)
{
switch (result)
{
case ShowResult.Finished:
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
DestroyImmediate(this.gameObject);
break;
case ShowResult.Skipped:
Debug.Log("player didnt watch the ad");
break;
case ShowResult.Failed:
Debug.Log("No Internet");
StartCoroutine(DisplayError());
break;
}
}
result.finished works as required but when i disconnect my internet connection showresult.failed dosent work forget the coroutine i dont even get the debug message of no internet, my unity version is 2019.2.6f1

Edit: it works when i disconnect internet it means ad is not ready so i needed to check if(!Advertisement.IsReady()) sorry for disturbing as i was stuck for 5 days in this

 

thank you so much guys...it been a great relif for me after the ad is working
update advertisement form package manger to 3.0.3
