Facebook Pixel: Products Are Missing From Your Catalogs

hi,

Please could you help with this issue. I set up a Facebook feed, and inside my Facebook shop it looks OK, there are products shown with multiple variants.

But looking at the Pixel Helper on any product page, it’s showing an error “Products Are Missing From Your Catalogs. Retargeting ads can’t run for 1 out of 1 product views on this page, because the products people have viewed are missing from your catalogs”

I can see Item Group ID is in the list of attributes. The feed link is https://dontwait.shop/wp-content/uploads/woo-feed/facebook/xml/facebook.xml

Do you know what is causing this?

Thank you!

Doug
