I use different shop pages with different product category but i can find the location of the show product number per page. I change the “Product Per Page” from Customize>WooCommerce>Product Catalogs page. But i cant find the “Product Per Page”. Now default value is 2! and i must increase it.
Woocommerce only supports configuring the number of rows and columns on each page.
So you can increase or decrease the number of rows + columns to increase or decrease product per page: https://prnt.sc/1thi5d4
Ex: You want to display 20 products on 1 page:
Number of columns: 4
Number of rows: 5
