Insert Interstitial between scenes and close the ad before changing the scenes in Unity,

Questions & Answers
1

I’m using AdMob interstitial ads, everything works fine. unfortunately the ad appears for about 1 second and disappears then scene is loaded. The user has no time to close the ad. What condition can I use if I want the scene to load only after the ad is closed?

using System.Collections;
        using System.Collections.Generic;
        using UnityEngine;
        using UnityEngine.SceneManagement;
        using GoogleMobileAds.Api;
        using UnityEngine.UI;
        using System;
    
    public class AdManager : MonoBehaviour
    {
        public static AdManager Instance { get; set; }
    
        
        private InterstitialAd interstitial;
        
    
    
    void Start()
    {
        #if UNITY_ANDROID
            string appId = "";
        #elif UNITY_IPHONE
            string appId = "todo";
        #else
            string appId = "";
        #endif
        
        this.interstitial = new InterstitialAd(appId);
    }
    
    public void ShowInterstitial()
    {
        RequestInterstitial();
    
    } 
    
    
    
    public void RequestInterstitial()
    {
        #if UNITY_ANDROID
            string interstitialId = "ca-app-pub-3940256099942544/1033173712";
        #elif UNITY_IPHONE
            string interstitialId = "unexpected_platform";
        #else
            string interstitialId = "unexpected_platform";
        #endif
    
        if(interstitial !=null)
        interstitial.Destroy();
    
        interstitial = new InterstitialAd(interstitialId);
    
        interstitial.OnAdLoaded +=HandleOnAdLoaded;
    
        interstitial.LoadAd(CreateNewRequest());
    
    }
    public void HandleOnAdLoaded(object sender, EventArgs args)
    {
        if(interstitial.IsLoaded())
        interstitial.Show();
    }
        
    
    private AdRequest CreateNewRequest()
    {
        return new AdRequest.Builder().Build();
    
    }
    
    
    }

//Change scene code I am using:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class ChangeScene : MonoBehaviour
{

public void LoadScene(string sceneName)
{
    
    SceneManager.LoadScene(sceneName);
    
}

}

The google docs:Anuncios intersticiales  |  Unity  |  Google for Developers
Under ad events, you will find an event called: OnAdClosed.
Add this event to your code and call the change scene script when that event fire.
