Contacted Shopify today but they were not able to help. I have the "request pending" for Shopify as a Pixel Analyst under the pixel that is connected and firing correctly on our store. When I go under Data Source - > Catalogs (under settings) it shows that I do not have any catalog (Company name does not have any catalogs yet) even though when I go under Catalog Manager the Shopify created catalog is there and working properly with all of our product shown.
@ggyaniv , I've done this and still have the pending status on the pixel.
What access did you give them when adding Shopify as a partner in your business manager?
PS: to anyone wondering, adding the Shopify business ID to a pixel used to work just fine. Now it apparently sends an invite for Shopify to approve, super frustrating.
