Facebook catalogue not getting populated with products from Facebook & Instagram pixel.

[DwayneA]

Good Day,

I have setup everything and all seems to be correct except the fact that my Facebook shops catalogue does not populated my inventory from my Shopify store. The Shopify catalogue is populated and updated fine from the same pixel.

No metadata errors, pixel is active and working. I can see products in Shopify catalogue but not Facebook shop catalogue.

Tried reinstalling Facebook & Instagram many times, it always creates its own catalogue and does not use my Facebook shops catalogue.

What am I missing, this is driving me insane.

Thank you kindly.
