@Sumanths1312 there is no exact timeline for any individual person. As was shared at https://brave.com/rewards-solana/ it is invite only to start. It will be going through some testing and gradually sending invites to people through the Rewards icon.
As you can see at Ads Payout Status Update the first group will be receiving the initial payout next month.
So I guess when you say officially getting the updates, the answer is now. However, only for a select few. Then it will just keep increasing until it’s available for everyone. Just keep an eye out on announcements and you’ll see when it’s widely available. And keep an eye out on your Rewards to see if the invitation appears for you.
