I spoke to the Payment team on the status of the invoice delivery. It seems there had been a processing error in the system; this has been resolved on our end however and the invoices are being sent out as we speak. They should arrive at your email provided in Ovi Publish by the end of this week at the latest.
If you have not received this document by early next week, please email the Publisher Support team once more. We apologize for the delay and thank you for your patience.
