It’s been a long time and I have face the same problem earlier before but no solution recieved, even though I have also reset my brave reward account as told by the brave support team but problem still persists.
Yes you are right, as earlier chatting with the support team they said that I have a previously opened account i.e. uphold account connected with it that’s why I am not able to receive the brave reward, and also said that to reset your brave rewards so I did the same but still can’t able to receive the reward.
