Interstitial Ads not showing admob plugin for unity

Question

I am trying to put an interstitial ad after every 5 games the user plays. What I've done is created an empty object with the following script:

using UnityEngine;
using GoogleMobileAds.Api;

public class AdBetweenGames : MonoBehaviour {
    InterstitialAd interstitial;

    void Start()
    {
        if(PlayerPrefs.GetInt("games-played", -1) % 5 == 0)
        {
            this.ShowInterstitial();
        }
    }

    private void RequestInterstitial()
    {
        string adUnitId = "UNITID";


        // Initialize an InterstitialAd.
        interstitial = new InterstitialAd(adUnitId);
        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();
        // Load the interstitial with the request.
        interstitial.LoadAd(request);
    }

    public void ShowInterstitial()
    {     
        RequestInterstitial();
        Debug.Log("Interstatial ad called.");
        if (interstitial.IsLoaded())
        {
            interstitial.Show();
        }
    }
}

I am sure the code here is called properly based on the debug log. I've also tried doing banner ads and they show without a problem after 1-2 seconds. I am making an android game.

Also I was thinking, could it be that the ad needs some extra time to load and I am clicking try again too early. But then what would a solution be?

ad mob的非页内广告需要时间来加载，以便在更新中尝试并等待至少4秒钟， ShowInterstitial在bool调用ShowInterstitial函数，并在开始时将其值设置为true ，然后在调用一次展示广告的函数后将其设置为false 。
