The button disappears when I hide add to cart

Yeah, me too. I hope in the next update the issue will be fixed. Thanks
I love this plugin.

I also had this problem. It appears to be because the Whatsapp button is using the same CSS selector as the add to cart button.

A temporary solution was to hide the cart button using javascript in the theme’s functions.php.

I used this code:

/**OCULTA O BOT?O DE COMPRAR DO WOOCOMMERCE SEM OCULTAR O BOT?O DO WHATSAPP*/
function custom_css_addition() {
    if (is_product()) {
        echo '<style>
                body.single-product form.cart button.single_add_to_cart_button {
                    display: none !important;
                }
            </style>';
    }
}
add_action('wp_head', 'custom_css_addition');

You may have to inspect the element on your product page to see if it is the same CSS selector. Good luck and I hope the developer fixes this. From what I understand, he just needs to remove these button classes as they are generating conflict with the same Woocommerce button classes.
