I'm checking my referral stats on the page here: [https://publishers.basicattentiontoken.org/publishers/home](https://publishers.basicattentiontoken.org/publishers/home?locale=en)
I shared my referral link earlier today with someone who used it to download and install the Brave browser. However, the referral stats on the above page does not reflect it. It still shows 0.
Also, it says: "Last updated 8 hours ago".
I'd like to know how often are these stats updated?
