Thanks for reaching out to us!
It seems like your friend hasn't completed their first payment yet.
As mentioned on https://www.commonlounge.com/referral, after your referred friends become active subscribers (ie. they sign-up for a full, paying account, not a trial account), a free month of CommonLounge Pro will be added to your account. This usually happens a week after your friend subscribes to Pro, since we offer a free 1-week trial to all users.
