WordPress – WooCommerce programmatically added fee don't persists

I am adding a custom fee to the cart by hooking into the woocommerce_cart_calculate_fees action like so:

add_action('woocommerce_cart_calculate_fees', function add_loyalty_discounts(WC_Cart $cart)
    {
   $cart->add_fee('Loyalty Discount',   -intval($_GET['discount']));
});

The fee appears on the cart page but not persist onto the checkout and order pages.

I’ve tried using $cart->set_session() but this had no effect.

    I tested and it works fine with me on both cart and checkout page

    function add_loyalty_discounts(WC_Cart $cart) {
        $cart->add_fee('Loyalty Discount', -intval(100), true);
}

add_action('woocommerce_cart_calculate_fees', 'add_loyalty_discounts');

    There are some mistakes, and missing things in your code, try the following:

    add_action('woocommerce_cart_calculate_fees', 'add_loyalty_discounts');
function add_loyalty_discounts($cart) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;
        
    $cart->add_fee('Loyalty Discount', -intval(100), true);
}

    Code goes in function.php file of your child theme (or in a plugin). It should work now.
