Give us a brief description of the ads behavior you’re seeing
I started using Brave in August, and received ads with no trouble until December. Since then, I’ve received maybe two ads total in almost two months. I’ve tried all of the trouble-shooting tips in the FAQ and in other posts, with no solution. According to @BraveSampson, at this moment there are 68 campaigns, 90 creative sets, 324 ads from 42 advertisers targeting United States, so there is no lack of ads to display. I have my Brave Rewards setting at 5 per hour and states turned off.
What OS/Brave version are you using?
Brave 1.19.88 Chromium: 88.0.4324.96 (Official Build) (64-bit)
