I have just confirmed a successful referral to one of my friends. He had created his own Evernote account and already installed the app in his own android tablet. I am sure that I have already satisfied the criteria as how a successful referral is confirmed. After this, I check on my points and I still had zero, which is I know, should have gotten up to 10 points because of my successful referral. What happened to my supposedly earned points? Am I still missing anything?
