I have, to date, made over 50 dollars from brave ads. However, on my new computer, I have yet to see a single one. If I could get any help I would be so happy!
Just browse as you usually do, @Qball. Brave will match your interest with the available ads catalog. It’s happens on your device, so, because you’re on new computer, the system need to “learn” about you first.
@eljuno How long should this take? I am getting a bit impatient.
This one 
If it’s matched, then you’ll see the ads.
