I use Paypal Payment PRO Service. I set Payment Action as "Sale". When someone orders, an order email is generated. An invoice is also generated automatically. But an Invoice Email is not getting sent. It says "the invoice email is not sent" in the Invoice Header. I have gone through couple of posts here but could not come to a conclusion yet so posting.
Invoice Emails are being sent when an Order is placed through "Check / Money Order" method. But not with the "Paypal Payment PRO".
Why the invoice emails are not being sent?
