Hi Henry, thank you for your response. My entire website consists of simple products. I have 850k products, but the plugin generates a feed file with up to 8 million products (I stopped and reconnected to Pinterest to regenerate the feed file). My text editor cannot open the entire file, but I can view the beginning of the file. At the beginning, all the information is correct, but the shipping fee in the latter part is not accurate as per what I have set up in WooCommerce.
