Product import in WP 5.3.2 and WooCommerce 3.9.1 seems to be broken. I make sure to tick the “Update Existing Products”. Once the process is completed it tells me that the products were imported. The result is a list of products without any SKU but with prices (I want to update the prices based on the SKU). The number of the newly created products seems to be equal to the number shown at the end of the import. Other products don’t seem to be updated.
