create account during checkout makes order not work

Dear SumUp devs,

I tried your plugin on my website and with a few transactions and it works. The payment goes well and I am redirecting to the order summary page of woocommerce.

However this process does not work if the user selects “create an account” during checkout. In this case, what happens is that as soon as “pay” is clicked, the money are withdrawn from card, the payment shows in SumUp Dashboard, but in Woocommerce nothing happens and the user does not go past the checkout page. So the order is never created, the user does not see the summary order woocommerce page, but the payment is done! In this situation, the emails of new order to the site owner and order processing to the user are not being sent because the order is not indeed created.

What is sent, however, is the confirmation email from wordpress that the user account has been created, with a username and a password. So it seems that these two functionalities are in conflict? With other payment gateways I have not experienced this issue. I tried for instance with Cash on Delivery and everything works, the order is created, the order email is sent and the account is created during checkout. That’s why I am writing here, because SumUp Gateway somehow conflicts with account creation during checkout.

Thank you for addressing this issue. I have latest version of plugin, WP, and WC.
