Yes it is still at the same location. Added the code:
// Change location of the checkbox
add_filter('anonymous_donation_checkbox_location', function() {
return 'woocommerce_after_order_notes';
});
Add checked if the following code was available in my plugin version
if (get_option("wcdp_enable_checkout_checkbox", "no") === "yes") {
// Add checkbox to WooCommerce checkout
$checkbox_location = apply_filters('anonymous_donation_checkbox_location', 'woocommerce_review_order_before_submit');
add_action($checkbox_location, array($this, 'add_anonymous_donation_checkbox'));
//Save the value of the WooCommerce checkout checkbox
add_action('woocommerce_checkout_create_order', array($this, 'save_anonymous_donation_checkbox'));
//Display the value of the WooCommerce checkout checkbox to the user
add_action('woocommerce_order_details_after_customer_details', array($this, 'display_anonymous_donation_checkbox_in_order_details'));
}
