YouTube videos don’t open in full screen!? Why are there so many weird issues with this browser? It’s unusable! This youtube issue was brought up over a yr ago and nothing has been done for the # 1 site for watching various videos on the web. That’s extremely troubling.
Mostly Brave is working fine for me, including videos in fullscreen mode on various different sites. Are you getting the bar at the top of the screen requesting permission to go full screen?
