I have gone through all the topics here related to my concern. However, I still can not find the ultimate solution for that.
My problem is Facebook Shop not showing all my product variants. I have 3 product collections with 6 SKUs per collection. However, Facebook shop just shows only 1 SKU with random price per collection. In addition, we apply Installment Price. Then Facebook shop takes the Installment Price instead of Full Price.
I have been waited for 72 hours (as provided information) as well as tried to uncheck then re-check the box again. However, the problem is still there.
Could you please help to advise us on this problem?
