I have spent so much time on this and triple checked everything, and i still cant publish my facebook shop to enable instagram shopping. I have no idea what i have done wrong but when i go to publish the publish button is greyed out. When I place the cursor over the greyed out publish button it says 'this cannot be published as my commerce account didn't pass the review'. Also when i go to my commerce account everything seems to be working fine. And when i go to my catalogue manager is says:
I've been struggling with the same thing.
I was still setting the shop up when I started the facebook integration to get the pixel going. I thought I'll do the commerce integration as well as its all combined now - big mistake as its triggered some kind of problem with the merchant agreement and I now get the same message.
I think it requires a human review at FB. Now we're in Q4 that's taking ages. I've been waiting more than a week for a response from Facebook support.
Would love to know if there's a different solution.
I'm having the same issue: Facebook customer service is terrible too I've requested 3 reviews, spoken to the business live chat and they just send you round in circles.
I found this: https://developers.facebook.com/tools/debug/
If you put the Shopify Product URL into the debugger, it tells you what Facebook may read as an issue with the page (i think!)
I got this warning:
