Its been over a week since using brave on my android device but I haven’t received a single ad notification yet.I read through your support thread.I have brave ads and rewards turned on and I am from India where ads are supported.
By enabling Brave Ads, doesn’t mean you’ll receive “as many Brave ads as possible”. Brave Ads is processed based on your browsing history and matched with the available ads catalogue.
It’s also depends on the availability of the ads campaign in your region. Brave Ads is not about “quantity”, but about “showing the right ads (for you), at the right time”.
