How do I set the limit of four products total?

Hi,

This can be done, however, you’ll need to assign all your products to some category or tag. After that you need to enable “Per product category” (or “Per product tag”) option in “WooCommerce > Settings > Maximum Products per User > Limits”, and then set “Limit per user” option for that category (or tag) (in “Products > Categories > Your category > Edit”) to the total number of products you need.
