I am unable to upload an invoice. I am on Windows 10 and I've tried both Edge and Firefox. After selecting a .jpg picture of my receipt, I click the 'Save' button. I can see that a POST is being made to secure.evga.com, but other than that, nothing seems to happen. I don't get an error or confirmation.
I'm just trying to do the free Powerlink deal, and honestly, it's kind of irritating that the serial number for my card isn't enough.
