Hi @johnhall6095
Let me explain you by giving a demo website example here. This is one demo website of Magento 2 "http://magento2-demo.nexcess.net/".
Home page: http://magento2-demo.nexcess.net/
Product Listing page of Women category: http://magento2-demo.nexcess.net/women/tops-women.html [when you select category and go to the listing page then it is product listing pageof that category]
Now check on sorting on product listing page, meaning in this demo website you can see the option of sorting in right top [http://magento2-demo.nexcess.net/women/tops-women.html]
If on this product listing page, the sorting is working and not working on home page then there is some issue of coding. It means we need to add sorting function in code.
Let me know if there is still any confusion.
