How to change button lable text on category pages

@kms-inc

So I am guessing that the products within that category are variable products?

https://docs.woocommerce.com/document/change-add-to-cart-button-text/#section-3

add_filter( 'woocommerce_product_add_to_cart_text' , 'custom_woocommerce_product_add_to_cart_text' );
/**
 * custom_woocommerce_template_loop_add_to_cart
*/
function custom_woocommerce_product_add_to_cart_text() {
	global $product;
	
	$product_type = $product->product_type;
	
	switch ( $product_type ) {
		case 'external':
			return __( 'Buy product', 'woocommerce' );
		break;
		case 'grouped':
			return __( 'View products', 'woocommerce' );
		break;
		case 'simple':
			return __( 'Add to cart', 'woocommerce' );
		break;
		case 'variable':
			return __( 'View', 'woocommerce' );
		break;
		default:
			return __( 'Read more', 'woocommerce' );
	}
	
}

Thanks for the quick response…actually no, they are simple products.

I have the same problem with the buttons.

I tried all three suggestions from https://docs.woocommerce.com/document/change-add-to-cart-button-text/
But it did not work.
How can I change the text?
Thank you very much.
