            }
            else
            {
                PlayerPrefs.SetInt("Adcount", PlayerPrefs.GetInt("Adcount") + 1);
            }
        }

        else
        {
            PlayerPrefs.SetInt("Adcount", 0);
        }
    }
    IEnumerator ShowBannerWhenReady()
    {
        while (!Advertisement.IsReady(placementId))
        {
            yield return new WaitForSeconds(0.5f);
        }
        Advertisement.Banner.Show(placementId);
    }
}

**i keep getting the error

Error CS0117 'Advertisement' does not contain a definition for 'Banner' ** EDIT: I got it working in test mode but when the I try it on my phone nothing pops up. I checked around and this problem has been happening to other people. I live in the US, so this feature should be working. Other people reccomend to use another type of ads. But unity ads is very convenient.

Banner ad example from Unity Docs:

using System.Collections;
using UnityEngine;
using UnityEngine.Advertisements;

public class BannerAdScript : MonoBehaviour {

    public string gameId = "1234567";
    public string placementId = "bannerPlacement";
    public bool testMode = true;

    void Start () {
        Advertisement.Initialize (gameId, testMode);
        StartCoroutine (ShowBannerWhenReady ());
    }

    IEnumerator ShowBannerWhenReady () {
        while (!Advertisement.IsReady (placementId)) {
            yield return new WaitForSeconds (0.5f);
        }
        Advertisement.Banner.Show (placementId);
    }
}
