Not receiving any ad notifications for Brave rewards on Mac OS Catalina 10.15.7

I have been using Brave for more than 3 weeks now. After multiple re-installs, checking all the notification settings, verified uphold account & even checked all the forums to fix but I haven’t been able to figure out why am I not receiving any notifications for ads on Mac OS 10.15.7.
And so ofcourse no rewards. :frowning:
Please help!!!
