1) We have created test order and don’t see the problem with autopayment. Before the autopayment, the new order is created according to settings http://prntscr.com/kbsk2y and then autopayment.
I saw the new order created 1 day before the payment due. I managed to achieve that myself too. The problem is I was given the impression that the auto payment will auto deduct from the same credit card without sending an email to the customer asking them to click ‘pay’.

2) The error appeared because of the incomplete variable product. When we finished the creation of the variable product it disappeared.
I am not too sure what do you mean by that? Cause I did not set up any variable product. Can you elaborate a little more about this. Thanks!
