Oh is it? India isn’t supported. I don’t know you even checked the page I shared with you to view supported regions for verification. You must’ve most probably checked if India is supported for Brave rewards Ads.
You can’t do much if India is unsupported right now. Brave is working on getting Brazil and India working again pretty soon though. I guess it’ll be 2 - 3 months from now but yea India should be back up working by then.
Also you can check for the updates at the PSA →
