Admob Errors

I am trying to implement Admob ads into my game from a recent tutorial. Under the NativeExpressAdClient script I am receiving 5 errors.

Externs.GADUSetNativeExpressAdCallbacks (
				this.NativeExpressAdViewPtr,
				this.NativeExpressAdViewDidReceiveAdCallback,
				this.NativeExpressAdViewDidFailToReceiveAdWithErrorCallback,
				this.NativeExpressAdViewWillPresentScreenCallback,
				this.NativeExpressAdViewDidDismissScreenCallback,
				this.NativeExpressAdViewWillLeaveApplicationCallback);
		}

The errors are coming from the bottom 5 lines. To give an example, for the line:

this.NativeExpressAdViewDidReceiveAdCallback,

I receive the error:

Static member ‘GoogleMobileAds.iOS.NativeExpressAdClient.NativeExpressAdViewDidReceiveAdCallback(System.IntPtr)’ cannot be accessed with an instance reference, qualify it with a type name instead (CS0176) (Assembly-CSharp)

This has been hurting my head and I’ve been searching for a solution for the last 2 days and had no success. I’ve tried reimporting the package multiple times. Any help is appreciated.

Changed the code to this:

Externs.GADUSetNativeExpressAdCallbacks (
				this.NativeExpressAdViewPtr,
				NativeExpressAdClient.NativeExpressAdViewDidReceiveAdCallback,
				NativeExpressAdClient.NativeExpressAdViewDidFailToReceiveAdWithErrorCallback,
				NativeExpressAdClient.NativeExpressAdViewWillPresentScreenCallback,
				NativeExpressAdClient.NativeExpressAdViewDidDismissScreenCallback,
				NativeExpressAdClient.NativeExpressAdViewWillLeaveApplicationCallback);
		}

The error went away but I’m unsure if the scripts will run the way they are supposed to. I will post again if the ads begin working.
