For anyone reading, for best compatibility longer-term I would suggest just using the [woocommerce_checkout] shortcode. Things are moving so fast and this typically ensures your code & design will last longer.
If you are using a funnel software for WooCommerce, I also prefer to use the shortcode, even if a page builder “supports it natively”… but updates always cause tweaks & changes out of your control.
This way your CSS & any JS will follow WooCommerce, rather than WooCommerce, your Builder & any other plugins enhancing the checkout experience.
This is the route I’ve chosen going with Bricks, and my setup is very enjoyable… don’t have to worry about Bricks updates, but get the Bricks experience when I want (most important is fast speed )
