Brave for Android, v1.0.42 (latest from Play Store). Turning on third-party cookies enables it for the current session only. If you exit the browser and re-launch it, the third-party cookies are disabled again.
Too many sites break with third-party cookies disabled so this makes Brave a good deal less useful to me than it could be.
- Launch Brave for Android
- Menu > Settings > Site Settings > Cookies
- Turn on “Allow third-party cookies” checkbox.
- Back, Back, Back
- Menu > Exit
- Launch Brave again and go back into the Cookies screen (i.e., repeat steps 1-2)
- Note “Allow third-party cookies” checkbox is off.
