Unity Ads Not Working?

I had Unity Ads all set up and ready to go. I played an ad every time a button was pressed on the Game Over screen. It was working completely fine until I installed Unity 2019.3.13f1. Now it doesn't show the dummy ads and when I connected it to my phone in Unity Remote 5, there were no ads there either. I'm not sure what's happening. Please help.

My ad code:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.SceneManagement;
3. using UnityEngine.Advertisements;
4. using UnityEngine.Audio;
5.  
6.  
7. public class GameOverMenu : MonoBehaviour {
8.  
9.     public AudioMixer mixer;
10.  
11.     void Start()
12.     {
13.         Time.timeScale = 1f;
14.     }
15.  
16.  
17.     public void GoHome()
18.     {
19.         SceneManager.LoadScene("Home");
20.     }
21.  
22.     public void PlayAgain()
23.     {
24.         SceneManager.LoadScene("MainGame");
25.     }
26.    
27.     public void ShowAds()
28.     {
29.         if (Advertisement.IsReady("video"))
30.         {
31.             Advertisement.Show("video");
32.         }
33.  
34.         if (Advertisement.isShowing)
35.         {
36.             Time.timeScale = 0f;
37.             mixer.SetFloat("Volume", -80f);
38.         }
39.     }
40.  
41. }

 

I'm not receiving any console errors. I use the ads when the player clicks play again or home on the game over screen(I'm releasing to the Play Store and my project is on Android). For the SDK, I'll assume you're talking about the package version, which is 3.4.5. About the initalization, I don't think I ever call the function, the only weird part is that I haven't touched my code and before it worked just fine, so I will have to look into that.

 

I got it to work by myself. Turns out all I needed to do was initialize the ads! Thanks for the help anyway!
