I'm trying to make a webshop with commerce 2.0 in Drupal 8.
But when I have added a product to the cart, and I've filled in the Payment Information pane, and I press "Continue to review", the same page is being reloaded and there's a duplicate of the product I tried to purchase.
So I'm stuck in the check out flow. If I disable the Payment Information pane, then I can continue in the checkout flow, but then I'm missing the payment information.
Does anyone have an idea for a work around or a fix? or maybe knows what's causing this?
