No more ads are showing up

I have to update this topic again:
After I’ve received ads for a few days. there ar no more ads showing up since Monday this week (3+ Days in total). Not even a single. I’m opted in to brave and i got my region settings right, just double checked and never changed. i’ve received ads in the past every now and then, totalling approx 5-10 ads a day. why didn’t i receive a single ad for the past 3+ days?
