The North Curve review for Google & YouTube

Update 5 Aug. Thanks to Shopify's in-house magician Jason, it's now working for the first time ever, and it only took a few straightforward changes. Many thanks Jason! Has anyone ever managed to get an advert running via this incredibly poor app? I've tried countless times but it would honestly be easier landing my car on the moon. Why do you need to link the app, Google Merchant Centre AND Google Ads just to get this to work; which it NEVER does. Any campaign I create just sits on 'pending' FOREVER.
