Hi there!
I just set up my ad account with facebook this evening in order to start a facebook retargeting ad through shopify that lives on in order to always be retargeting my customers on the FB platform. However when I created a campaign in shopify it keeps giving me this error message and I have gone through so many blog posts etc to figure it out but have never been more lost. Is any developer out there able to help make sure my pixel is set up correctly on my site etc? and why this campaign keeps erroring out?
