Hi @selwynnz,
I will be happy to help you.
But firstly, I would appreciate it if you, in the future, create a new thread, so it is easier to keep the different cases separate.
With that said.
To use display style “Add to cart button” it requires that within the woocommerce settings under products that “Enable AJAX add to cart buttons on archives” has been checked.
So if it is not checked, that’s why they don’t work.
But if it is checked, then I would like you to send me a link to where I can test it so I can try to see what is wrong, and if I can get you to create a new support thread around it, I will be happy.
Best regards
Frederik
