IOS Ads not Displaying yet Audio Present,IOS Ads Not Displaying Yet Audio Present

I've become incredibly frustrated with the ad implementation system in unity. I think I finally have it figured out except I can't see the video ad, only hear the audio. It's being recorded as an ad view in analytics, but is not visible to the user. I believe it may be rendering behind my other sprites, but have not been able to rectify this by manipulating the z axis or changing the layer. Any help would be greatly appreciated. Below is the code snipped I copied from the website. I'm using the latest 2019.1 f2 version of unity and the 3.03 ad services version from the asset store. I am building to an iOS device, the preview looks fine in the editor.

using UnityEngine.Monetization; public class scoreKeeper : MonoBehaviour { string gameId = "3130668"; bool testMode = true; public string placementId = "video"; public void ShowAd() { StartCoroutine(ShowAdWhenReady()); } private IEnumerator ShowAdWhenReady() { while (!Monetization.IsReady(placementId)) { yield return new WaitForSeconds(0.25f); } ShowAdPlacementContent ad = null; ad = Monetization.GetPlacementContent(placementId) as ShowAdPlacementContent; if (ad != null) { ad.Show(); } },I've become incredibly frustrated with the ad implementation system in unity.
