This was a known issue and overall resolved for anyone who has kept their browser updated and active. What version of Brave are you using?
FYI, around 1.40 they asked everyone to update and then to leave the browser open as much as possible so it could sort itself out. The majority of people have had payment issues resolve, though not for everyone.
Regardless though, if you ever have issues in receiving BAT, then you should create an official Support Ticket so someone from Brave can review everything and try to get you everything.
