WooCommerce custom PHP code to change Add To Cart button text

Question

I want to update the default 'Add To Cart' text to be more suitable for my website. I have created a child theme using Astra, installed it, and then on the Theme Editor in WordPress I added a new function to my functions.php file that should have done the trick

add_filter( 'woocommerce_product_add_to_cart_text', 'woocommerce_custom_product_add_to_cart_text' );  
function woocommerce_custom_product_add_to_cart_text() {
    return __( 'Check it out', 'woocommerce' );
}

From all the examples online it should be this easy. I just read from another post that this may be deprecated now? Should this still work, anything else I can check? I want this to be the button text globally on all products but each product still shows 'Add To Cart'. I saved and then reloaded my website but do not see any changes

Answer 1

add_filter( 'woocommerce_product_add_to_cart_text', 'mujuonly_add_to_cart', 10, 2 );
add_filter( 'woocommerce_product_single_add_to_cart_text', 'mujuonly_add_to_cart', 10, 2 );

function mujuonly_add_to_cart( $text, $class ) {
    return __( 'Check it out', 'woocommerce' );
}
