I have recently setup autopay and all of my customers have scheduled their monthly payments. Problem is the invoices are due on the 1st of the month, but they are complaining because their payments are being deducted 2 days earlier than the due date. How can I change this? 

I've tried changing the "create number of days in advance" from 2 to 0, but the system won't retain the edit... please tell me there is a workaround so I don't have to ask them all to re-sign up for autopay??
