We are testing magento 2.0.1 and when using authorize.net direct post, we have set the order status to be processing after capture yet once the order is placed, the status is always pending and we have to manually send out invoice for the order to become processing. Also, for each single order placed with authorize.net direct post, there is a duplicate order around 10 seconds apart with the same order information. If we use check or money order as payment, there is no duplicate orders.
Does anyone have any idea what could be wrong?
Thank you!
