I have received full creator rewards, including last 2 months. The payment delay was so long, I tried to reassure myself that Brave was just being late for trouble, not a scam. But it must be said that it is the slowest payment I have received.
If you are also waiting for a creator payment, please wait patiently. As far as I know, the payment process will be done continuously for a period of 6 to 8 hours.
