As far as I know, the Sharing program needs to use referral links so if the referral function is still upgrading, how do we know that if our friends come to your site from the link that we shared with them?
Maybe the referral or inviting needs to finish the upgrading process first before sharing this news to the other website.
Besides that, many of us will share the news on our social media or other websites so if the link tracker is not active, I think we will not see if that can work or not.
Thye should fix this as soon as possible, other casinos already have referral link banners, and promotional materials before they launch their project, the worst thing is you have friends who are looking for profit-sharing casinos and you cannot refer your friend here immediately because you're not going to get anything from referring them, and before you refer them with your link they already sign up because they have a campaign here.
