Guys I got to the customizer and click on the global CSS editor and all of my existing CSS is not there? It seems to be working I just have no idea how to access it and make changes. So where do I got to find my old rules that were right there in the customizer before the new css thing was activated.
Also move the edit point to the center of the page or at least up a bit. Right now its in the bottom most left point of the screen and it beaning hidden under the windows task-bar, check it out:
