Hello @Pakyntein,
Brave is working to make sure as many regions as possible are supported.
If your region is not currently supported, be patient, as it is a work in progress. Some regions that were previously supported are no longer supported for the time being.
For more information, visit PSA: Unsupported Regions as this contains the information that you seek.
Please also consider using the search feature to look for issues before making your own thread, as there is a large amount of posts that cover a wide array of issues.
Cheers!
