In my category pages, I would like to mix the order of the products to be random.
I was adding products to my site by "Brand". Now if I click on "T-Shirt" category, first 5 pages is Adidas only, then next 5 pages it's Puma etc. I would like to mix the products in all my categories to be totally random.
Category pages have products randomly displayed. So for example, page 1 in "T-Shirt" category, will have a mix of all the products within this category in random sort order.
Using Magento 2.1.8 and custom theme.
