Error: Brave Rewards profile has been flagged
Unfortunately, your Brave Rewards profile has been flagged and you are unable to verify with a custodian at this time. This flag could be due to illegal activity on Brave Ads, but it could also be a false positive.
Important: While your Brave Rewards profile is flagged, you will not be able to verify.
No action from you is required. Your Brave Rewards profile will be automatically re-evaluated on a regular basis to determine when (or if) the flag can be removed. Try again from time to time to see if the flag has been removed.
