Hello,
1.) what is the short code to show ALL recent products for pro?
is it: [wcv_pro_recent products] ?
If you want vendor specific products, you use our shortcodes. If you want to show ALL products from ALL vendors, you use WooCommerce shortcodes. https://docs.woocommerce.com/document/woocommerce-shortcodes/
2.) how can I tweak that to display only 12 recently added products?
is it: [wc_pro_recent products per page=’12’]
WC Vendors and WooCommerce shortcodes both accept arguments for number per page for most of the shortcodes.
For WC Vendors it would be: [wcv_recent_products vendor=”VENDOR-LOGIN-NAME” per_page=3]
For WooCommerce: [recent_products per_page="12" columns="4"]
