Cloud build with Unity Ads fails with Error Error cs0246

Could someone please send me a .gitignore file that will work.
Any other ideas would be great.

I'm using Unity 2019.2
Ads v 2.0.8 installed with PackageManager
Building for iOS
from github repo

Here's the build log error:
**6: [Unity] Assets/Scripts/Adverts.cs(60,35): error CS0246: The type or namespace name 'ShowResult' could not be found (are you missing a using directive or an assembly reference?)**

It builds fine on a local build for Android.
I don't have an iMac
I've tried removing and reinstalling Unity Ads
I've tried a clean build
I've tried including Library/PackageCache in my repo
