Please add Quad9 188.8.131.52 DNS server as one of the default Brave android browser DNS-over-HTTPS (DoH) options. Because today it is one of the most popular free dns server, in addition to Cloudflare, Google Public DNS and OpenDNS, which you already support. Thank you.
The list of DNS/Https comes from upstream Chromium, we (Brave) don’t add/remove these. @johnbrook
