same here, getting a lot of these warnings since a few days:
PHP message: PHP Warning: Undefined variable $should_use_billing_info in /var/www/html/public_html/wp-content/plugins/facebook-for-woocommerce/facebook-commerce-iframe-whatsapp-utility-event.php on line 87
just realised that this is only happening for users which are logged in. If they are not logged in, it will not be published and I have to moderate it first. So I guess this will be fine for me
Ok wow… I also added the website with “www.” to the stripe settings but nothing changed.
2 hours later I reloaded my website and the “Apple Pay” button is now there. Don’t know what was the reason or what happened but for now my issue is resolved and this ticket can be closed.
