WooCommerce

i created lot of woocomerce website and with all always i am facing a one issue- i can’t apply a coupon from url if cart is empty.

i created a emails which land user to shop page with coupon in url and i want to auto apply coupon in cart when something user will add to cart but not happening

i tried lot of plugin and stackoverflow code but nothing works coupon auto apply from url only if something in cart.

like in shopify if user land from coupon url on any page than shopify auto apply coupon cart and show when something added in cart
