thank you for your reponse!
I do have another question:
When I use amazon pay on the cart page and login into my amazon page I get redirected back to the checkout page where I select payment method and address.
Now when I go back to the cart page for example and click the usual “proceed to checkout” button I am again in the amazon checkout where I select payment method and address of my amazon account. So basically that means I am stuck and cannot change to a different payment method like paypal.
Is that intended? How can I change it?
