My friends installed the desktop app, but we still haven't received the referral space.

Thanks for posting this on our forum, massiecd!

Besides installing the Dropbox app on their computer, did they also verify their Dropbox email address? This is also necessary to ensure that you’ll all receive the referral space. 

Keep me posted for any updates.

Hey Nancy, they said they did and installed the Desktop app, signed in and everything. 

I see, thanks for clarifying! As a test, can they try to verify their email address once more from the link provided here and let me know if anything changes?

If not, I can go ahead and log a ticket for you next.

Still shows the same even after they verified. 

Hey massiecd, I just sent you an email! 

Reply back to me as soon as possible, and we'll investigate there. Thanks!
