Facebook Ads Expo - Ad was re-loaded too frequently

I am trying to implement Facebook Ads on my Expo app.

I have added the following to my app.json

"facebookAppId": "00000000000000",
"facebookDisplayName": "MyAppNameHere"

I have then created my placement ID's in the Facebook console and added the ad like this in my app following the guide here..

https://docs.expo.io/versions/latest/sdk/facebook-ads/

import * as FacebookAds from "expo-ads-facebook";
FacebookAds.AdSettings.addTestDevice(FacebookAds.AdSettings.currentDeviceHash);

<FacebookAds.BannerAd placementId="PlacementIDHere..." type="standard" onPress={() => console.log("click")} onError={(error) => console.log("error", error)} />

I am then getting the following error when I go to the view, does anyone know why this is? My app is still in review on the Facebook page, could this be it?
