I am having issue with brave browser not showing any ads, means not increasing my rewards, also my target location setting just disappeared, I see people having same issue and waiting for brave support to give solution/fix.
I did few things like reinstalling, clearing cache following all instruction for win 10 notification, assist focus and nothing works. The only thing that work for me to start seeing ads and increase on the rewards is to Create a new windows user/profile and start using brave browser, it start fresh as in 0 reward, but it now show ads, this might not be a good fix but a thing to look at.
Hope this helps…
