While I’m in the same location, Brave browser on my laptop says “Sorry! Ads are not yet available in your region.”, but on my Brave iOS application it works fine and I received 6 ads this month.
Brave is up to date
Version 1.2.43 Chromium: 79.0.3945.130 (Official Build) (64-bit)
I don’t use VPN, so why it doesn’t work on the browser?
