I've given referrals to the other members of the family to get some extra storage space on my basic account, and there was a truckload of problems with it.
Firstly, when trying to install the desktop app, which is necessary to complete the referral, it would only open MY dropbox, and automatically log them out of their web accound and override a login of my account.
To circumvent this, we had to uninstall the desktop app from the computer, log out of my account, log back in on their account, and then reinstall the desktop app, (which took a while of tinkering, because logging back in on my account before the app was fully installed just reset the whole thing, so it took 3 tries to do this).
After completing this, I log back into my account to check the referral status, and it says "inelegible"
Another unrelated issue is that when I look at my account settings, it says under timezones that I am in GMT+2, which is wrong, I live in Norway, which is GMT+1.
I checked a bit back and forth with this, tried setting it to UK which is GMT+0, and it thinks that is GMT+1.
In conclusion, the account settings believe that timezones are 1 higher than they are.
