Not sure when it started, but I've already noticed some Start Menu fuckery with just the 'Sign Out' portion. I believe you previously just clicked on your profile picture/name and the options for signing out were right there. They've "helpfully" hidden those options now beneath a ••• menu for no apparent reason. I was a little aggravated when I first noticed it because it seemingly changed out of nowhere. Not a huge change, but it requires one more click to do now.
