Issue that stops showing notification Ads in Windows 10

Would love to test Brave as my daily browser but I just can’t seem to find a solution for Brave Rewars to work. I have done pretty much all I have found on the web and still not a single notification showed up.
Just to clear it out, I am using Brave for Ipad and for Iphone and they all show Ads regularly, no problem with that.

I come from Poland, using Brave on Windows 10, I have English language set as my default OS language. Even switched date and region to match English, but nothing happened.
