Guys,
The check-out procedure is still not correct. Customers receive an order-confirmation (STILL) just after they press the pay-button. It does not matter if they pay it or what the return-code of the payment-provider is. In my opinion this is not correct. After going into the order-screen of the customer you see the order as "Unpaid", but there is no possibility to pay the order from here.
