Woocommerce how to enable product gallery features in Tienda

Just noticed that product gallery features lightbox etc have been disabled in Tienda. Anyway round this? I’ve tried adding this code to functions.php, but doesn’t seem to work.

add_theme_support( ‘wc-product-gallery-zoom’ );
add_theme_support( ‘wc-product-gallery-lightbox’ );
add_theme_support( ‘wc-product-gallery-slider’ );
