I have converted my Magento 1.9 to Magento 2.3.1. In Magento 1.9, the products are listed by the position as the following orders 0,1,2,3...10.. and so on. But when I check in Magento 2.3.1 site, all products are listed opposite, they are now listed in the order 10,9,8,7...2,1. How can I get products to be display by position as 0,1,2,3,4 in category page?
Please check with this url, for after upgrade facing this issue.
i hope its work for you.
