It’s not a special pro feature. If you write about WooCommerce, look at the Custom post types or WooCommerce group. There is “Orders” group there, which includes “edit_shop_orders” user capability and others, related to the shop orders editing.
Yes it allows them to edit but not create. We want them to be able to create an order.
WordPress does not use a separate user capability like ‘create_shop_orders’ for “Add Order” button protection. You have to turn ON a special option at URE Pro for this, for example. Be default ‘edit_shop_orders’ capability is enough.
You can try to temporally deactivate all plugins except WooCommerce and test if user with ‘edit_shop_orders’ capability will can to add new order. If ‘Yes’, activate plugins back one by one with new test to isolate a reason.
We have tested and no it does not work. when we click add order it loads a page and say “Sorry, you are not allowed to access this page.” So the default way does not work. So them it is a pro feature?
