第一次单击购物车页面woocommerce上的更新购物车按钮后，优惠券代码未删除

Question

I want to apply discount on 12(quantity) and remove discount below 12(quantity). I have created one coupon code for 20% discount('genew'). I applied and removed coupon code on when some one is clicked on update cart button on cart page(woo-commerce). Remove coupon code function is only work when someone click on update cart button two times. one first click it is not remove the coupon code.

Here are function that I am using in function.php

add_action('woocommerce_before_cart_table', 'discount_coupon');
function discount_coupon() {
global $woocommerce;
global $count_cart_quantity;
if ( $count_cart_quantity >= 12 ) {
$coupon_code = 'genew';
if (!$woocommerce->cart->add_discount(sanitize_text_field($coupon_code))) {
    $woocommerce->show_messages();
}

}

if ( $count_cart_quantity < 12 && $count_cart_quantity > 1 ) {
$coupon_code = 'genew';
if (!$woocommerce->cart->remove_coupons(sanitize_text_field($coupon_code))) {
    $woocommerce->show_messages();
}   

}

}

You should combine these conditional statements into one, comprehensive statement:

add_action('woocommerce_before_cart_table', 'discount_coupon');
function discount_coupon() {
    global $woocommerce;
    global $count_cart_quantity;

    $coupon_code = 'genew';

    if ( $count_cart_quantity >= 12 ) {
        if (!$woocommerce->cart->add_discount(sanitize_text_field($coupon_code))) {
            $woocommerce->show_messages();
        }
    }
    elseif ( $count_cart_quantity < 12 && $count_cart_quantity > 1 ) {
        if (!$woocommerce->cart->remove_coupons(sanitize_text_field($coupon_code))) {
            $woocommerce->show_messages();
        }
    }
}
