I have reproduced the problem, the function is not working again. It happens after I rebooted my computer and started Brave. Two fingers function for both normal and incognito are not working.
Did several restart Brave and/or restart computer, no changes.
For your information, two finger functions which are not working is as follow:
Google Maps: scroll up and down --> zoom in and zoom out
Whatsapp: scroll up and down in left windows, scrolling in right windows is working normally.
Telegram: scroll up and down in left windows, but scrolling in right windows is working normally.
Appreciate if someone can share how to solve this problem.
@adaryanto sorry to read this. Again, try it inside an incognito-window. If it works there you should check your extensions.
In a regular window, head over to brave://extensions and switch all your extension to disabled. Check the behavior. Will it work, re-enable your extension one by one, with a shot check in between. So you’ll be able to identify the extension(s) wich gives you trouble.
