Does console log indicate that Ads was initialized? You should have a message like following:

/Rasmus

I delete MyProject–>ProjectSettings folder and advertising play, but my UnityAdsEditor:Initialize is not True.

My Script

using UnityEngine;
using UnityEngine.Advertisements;

public class AdPlay : MonoBehaviour
{
    public void ShowAd()
    {
        if (Advertisement.IsReady())
        {
            Advertisement.Show();
        }
    }
}
