Cart item not removed after set_quantity to 0 with woocommerce_cart_item_removed

Hello.

The case is that I have an add-on product that could not be purchased as a stand alone product. It is a simple product but with different shipping class: ‘3-5days’. With this class I’m distinguishing what type of product I’m dealing with. So when I have in the cart simple product and add-on product I want to remove both of them when I remove the simple one.

Example:
Two products in the cart
simple product: Laptop
add-on product: Speakers
Action : Remove the Laptop
Back-end: I’m hooking towoocommerce_cart_item_removed. Then checking if there is add-on in the cart. And if there is – I’m removing it as well.

But the issue is that when i set the quantity of the add-on product to 0 (and everything goes well) I still have the add-on product in my cart.

Here is my code:

/*Hook on removing item from the cart*/
add_action( 'woocommerce_cart_item_removed', 'remove_addons_wsh', 10, 2 );
function remove_addons_wsh( $cart_item_key, $cart ) {

    //check if current product that is removed is the add-on product
    if( has_term( '3-5days', 'product_shipping_class', $cart_item_key ) ) {
        return true;
    }

    //find number of add-on prodcts in the cart
    $addon_count = 0;
    $addon_ids   = array();
    foreach ($cart->cart_contents as $cart_item) {
        if (has_term( '3-5days', 'product_shipping_class', $cart_item['product_id'])) {
            $addon_count++;
            array_push($addon_ids, $cart_item['product_id']);
        }
    }

    //check if overall count of products and the addon count
    if ( (count($cart) -1 ) > $addon_count) {
        return true;
    }

    //any other case - we remove all addons
    foreach ($addon_ids as $id) {
        $res = $cart->set_quantity($id,0);
        error_log("res:" .$res); //this does return 1(true)
        return true;
    }
}

Where might be the mistake,I tried different hook like woocommerce_remove_cart_item but still no good. I have tried $cart->remove_cart_item($id) and still no result;
