Hi Dave,
I know where the problem is. The product ref is only saved when creating a new product. Then, if you edit the product and update the product ref, at this time the new product ref is not saved. It still shows the old product ref in order description. Do you have any idea about this ? (it happens in both version 4.3.2 and 4.3.4)
Thanks.
Regards,
Phuoc
