Brave Nightly ads

Hello, my brave nightly is showing some ads, but they aren’t counting towards my rewards, it keeps showing 0.
When i created my rewards “profile”, i set the country to the US, cause i want to get the most amount of ads as i can, but i’m not living in the US at the moment, could this cause some issue?
Apologies for my english, this is not my first language, thanks in advance!
