I referred a friend a while back to join Dropbox, but he lost the email which has the sign up invitation. I tried to resend the invitation today, but Dropbox says that the email is already invited. Now my friend signed up with the same email and installed Dropbox desktop app as well, but both of us didn't receive the referral bonus. I checked the status, and it's not updated and showing "Invitation sent". How to resolve this issue?
Please guide.
Thanks.
