Hi there,
I’ve figured it out. It was actually an issue with the Stripe Payment Gateway within Woocommerce.
To resolve the issue, you need to remove the Buy Now element.
You do this as follows:
Go to:
Dashboard>Woocommerce>Settings>Payments>Stripe>Manage
Untick Payment Request Buttons
Click Save
Hopefully, that should resolve it,
Cheers,
David
