@Faiz025 the notice on the devices are just timed to show when payments begin. They never have had it accurate enough to ping each individual person as payments are sent. Before you created your topic here, you should have seen the very big banner that is on this site, which looks like below:
As it says, payments are still pending. Payouts only ever begin around the 7th of each month, but they can take a few days or even longer. Just keep an eye out on Ads Payout Status Update for updates.
If that post I just linked to ends up saying payments completed and you haven’t received, then you will need to create a Rewards Support Ticket at https://support.brave.com/hc/en-us/requests/new?ticket_form_id=360001302431 but please wait until it shows as complete before you do that.
