Last night, I updated Brave to Version 0.65.121 Chromium: 75.0.3770.100 (Official Build) (64-bit), on Windows 10 Pro, 1903.
I previously had WebRTC IP Handling Policy set to “Default”. Now it is set to “Disable non-proxied UDP”. When I try to set it to “Default”, after I reload the Settings page, it is back to “Disable non-proxied UDP”.
To reproduce, go into Settings -> Additional settings and set “WebRTC IP Handling Policy” to Default. Then reload the settings page, and the policy will be back to “Disable non-proxied UDP”.
Here is a GIF of what I see:
