Hello,
I referred my friend to Dropbox (they didn't have Dropbox) and they installed it from the link I sent them and started using it, but I didn't get the extra storage space I should get for referring a friend saying that it is ineligible.
We don't have the same IP address as they are in a different country and we none of our accounts were opened on the other's computer.
What is the reason for them to be ineligible?
