I invited my friends to the LingQ and some of them already registered here. But not all of them appears on my referral page.
Also I noticed that “Referral” field on the registration page is empty though person is visiting LingQ by referral link.
Is it necessary to clearly indicate referral code on registration page in case of using referral link? Something wrong in that process. “Referral” field should be automatically filled when people coming to the site by referral link.
How can I get back those referrals?
