Hi. 
I am not sure at what point in the process you are talking about. It appears from the information provided:
- You are still receiving ads and earnings
- When payouts are processed each month, your earnings balance is not processed
- During payout processing, your estimated earnings roll over to the next month.
Is this correct? Please clarify and provide more detail on what you mean when you say you are not receiving brave rewards.
If you are NOT receiving ads and/or earnings, have you read the Help Center topics linked at the top of your post to try and troubleshoot? can you provide more detail and the things you have tried? Also, using a vpn, especially if you are changing your country location, can get your account flagged. If your account is flagged, you will not receive ads and/or earnings.
Below is a link to a quick reference of typical issues for not receiving ads that you might try if you are not receiving ads.
