Brave Rewards stopped coming

Great thread. I am adding my similar case. Not getting ads since August. The issue has not been resolved yet.

Logs reveal constantly

VERBOSE2:permission_rule_util.cc(25)] You do not have enough unblinded tokens
INFO:ad_notification_serving.cc(109)] Ad notification not served: Not allowed due to permission rules

The browser wants to redeem unblinded tokens:

INFO:account.cc(206)] Retry redeeming unblinded payment tokens
INFO:redeem_unblinded_payment_tokens.cc(80)] RedeemUnblindedPaymentTokens
VERBOSE2:redeem_unblinded_payment_tokens.cc(89)] PUT /v1/confirmation/payment/{payment_id}
VERBOSE6:redeem_unblinded_payment_tokens.cc(99)] URL Request:

Content: {"payload":"{\"paymentId\":\"#mypaymentid#\"}","paymentCredentials":[{"credential":{"signature":"XXX","t":"XXX"},"publicKey":"XXX"}#longjsoncontenttruncated#}]}
  Content Type: application/json
  Method: kPut

But then getting:

INFO:redeem_unblinded_payment_tokens.cc(110)] OnRedeemUnblindedPaymentTokens
VERBOSE6:redeem_unblinded_payment_tokens.cc(112)] URL Response:

INFO:account.cc(202)] Failed to redeem unblinded payment tokens

Entering https://ads-serve.brave.com/v1/confirmation/payment/#mypaymentid# into the browser returns:

{"statusCode":400,"message":["nonce must be a UUID","nonce must be a string"],"error":"Bad Request"}
