I installed the brave browser in the beginning of January 2021. When I click “view monthly statement for details” I see zero BATs earned during January and February. How is this possible? I know that I have earned at least 3 BAT during each of these months. Do I need to claim my BATs I earned from ads otherwise they will expire?? I have not reinstalled the brave browser or in any way reinstalled/updated my system. Does any one of you have the same issue?
