I have configurable products in my PLP and I want to sort with "special_price" attribute.
I edited the special_price attribute from admin and allowed it to be sortable in storefront. But I am facing issue that it is working only for simple products and not for the Configurable products.
Also I can see an open issue on github similar to this - https://github.com/magento/magento2/issues/15609
Has anyone also ran into the same anytime, if so please help.
