I’m on IOS 26.2.1, brave Version 1.93 (136).
When you go to youtube.com, it redirects to the mobile site. Even with “request desktop site” turned on.
I started having exact same problem on my iPad also about a week ago, at first logging out clearing cookies worked but the second I logged back in it would go back to forcing mobile. I am using brave browser version 1.90.2.
Now it’s forcing mobile even when logged out, requesting desktop in brave browser is no longer working on iPad
