When?
Payments aren’t finished yet. You see the big banner on top of the website, right?
Payments are still ongoing. Until it says all payments are complete, we wait. If it says complete and you have not received it, then you create a Rewards Support Ticket at https://support.brave.com/hc/en-us/requests/new?ticket_form_id=360001302431. You just have to learn to be a bit patient.
Payments always begin around the 7th of each month, but they can take up to 3 weeks to process and arrive. This is especially true for the newer ZebPay.
