Google pay button

Hello,

I have instaled this plugin and it works fine in my site. I am having some issues with google pay. I have enabled it in the product, cart and checkout pages, but the button only is shown in the checkout page, in the other places when I inspect the code I find only this test:
<!– A Stripe Element will be inserted here. –>
but not the button code.

Is it a limitation of fee plugin? I would like to know if it is fixed in the pro version before to purchase it. In my site I work with Avada theme.

Best regards
