I am using Magento 2.0.4 and finding a way to automatically mark the order status to 'Complete' once the payment is complete.
At the moment what is happening is once the payment is complete the order status is marked as 'Processing' and once the admin opens the order and provide some comments and submit the order becomes 'Complete'
I do not want admin to do this manually. How can I complete the order as soon as the customer complete their payment.
