Hi there, my store website is https://golapi.co/
Facebook Shop Page: https://www.facebook.com/golapi.co/shop/
I have added the Facebook Shop sales channel to my store and it is synced properly. The collections are also ticked so that they are available to the Facebook Shop channel. However, if you go to the Facebook Shop Page, you can see that all products are grouped under "All Products" and nothing shows up for the "Women" and "Men" collections, although those collections exist in Shopify store. For some reason, the collections information is not being synced properly between Shopify and Facebook Shop.
