I could never go back to not using this but unfortunately the feature to automatically switch to 1440p on yt doesnt work. The only thing that switches to 1440p is if you pick a different resolution for full screen lets say 2160p and also check the option to switch back to default after exiting fullscreen. If I just load a fresh video its set at 720p and doesnt change by itself at any point during playback unless I go in full screen.

And now that im doing tests, most resolutions just dont apply automatically either. Its only the 4k one that has been reliable over the years, which has been my default for a long time.
