Guys I don't understand this at all. The guide somone put up on the previous page also appears as white blank image loading. What 6 digit code? What authentication app? I got the email and saw no 6 digit code, so I thought I must have to scan the QR code. I got a QR scanner for my ipad and scanned it, it only produces an invalid link which leads to nowhere? Where do I obtain this 6 digit code? What app should I be using? I made this account only to ask about this. Thank you in advance for answering.
