Hello,
I saw the screenshot you attached. The Payments are controlled by WooCommerce and our theme doesn’t influence.
It seems that you are using a third party plugin to add the stripe apple pay button. Please check the functionality with the default WordPress Theme just to check whether the issue is with our theme or not.
If it works fine with default WordPress Theme then provide with admin panel login details of the website to check it myself and help you out accordingly.
Regard’s.
