Please explain, How you solved your problem. I am also facing the problem in menu.
In your plugin folder Go To woocommerce->includes->wc-template-functions.php Now press ctrl+f and write woocommerce_order_review and press enter. You will find a function of the same name. Just remove its body(portion that comes under{}) And its done.
oh thanks, That was my silly mistake. As you said i was logged in as admin in chrome that’s why inquiry button was not displaying.
