Why don't I receive any ads?

After brave browser has introduced ads in the mobile app, I haven’t received a single ad. Is it just me or everyone not getting ads.

I want to generate revenue from ads. I need help.

Thanks.

@Emonsaqibh first, did you live in supported regions? For now, Brave Ads is geo-restricted to US, Canada, France, German, and UK.

EDIT:
With more regions support is coming.

Oh no. I live in Bangladesh. I hope my country starts supporting soon
