After updating Aardvark my style customisations are not working

There has been a change to the way the Aardvark Child loads the parent and child style.css files. You will need to update your child theme functions.php to fix this. Find:

/**
 * Load parent style.css
 *
 */
if ( ! function_exists( 'ghostpool_enqueue_child_styles' ) ) {
    function ghostpool_enqueue_child_styles() { 
        wp_enqueue_style( 'gp-parent-style', get_template_directory_uri() . '/style.css' );
    }
}
add_action( 'wp_enqueue_scripts', 'ghostpool_enqueue_child_styles' );

Replace with:

/**
 * Load child theme style.css
 *
 */
if ( ! function_exists( 'ghostpool_enqueue_child_styles' ) ) {
    function ghostpool_enqueue_child_styles() { 
        wp_enqueue_style( 'ghostpool-style', get_template_directory_uri() . '/style.css', array(), AARDVARK_THEME_VERSION );
        wp_enqueue_style( 'ghostpool-child-style', get_stylesheet_directory_uri() . '/style.css', array( 'ghostpool-style' ), AARDVARK_THEME_VERSION );
        wp_style_add_data( 'ghostpool-child-style', 'rtl', 'replace' );
    }
}
add_action( 'wp_enqueue_scripts', 'ghostpool_enqueue_child_styles' );
