Since I want to re-publish new pricing, I want to delete it and then upload it again. The SKU is fixed. One SKU entered into the system corresponds to one product, so I can't change it. Now I can't upload it. It shows that there is a copy of the SKU. I'm very distressed. Because I have deleted the product and re-uploaded it before, the SKU of the deleted product can be used to upload the new product without any problem, but now the upload fails. Can anyone help me?
