I'm either missing something or totally confused. I use Win11 on a Samsung laptop and want to mirror a tab to my tv. Unless I have a supported app (eg Youtube) open I am missing the "cast" ability. When I do have a supported app I get an icon near to the top RH which opens a box with cast availability. I'm pretty sure that I have had the option to mirror a tab previously. What has changed or what am I doing wrong. When I open the hamburger menu there is no cast option inder any condition even though the Google help instructions say that it should.
