Switching between graphics cards

I have two graphics options, INTEL and NVIDIA. I used to be able to switch the cards via the graphic icon in the applet section of the desktop. Now, I have to use the terminal with the PRIME command and then log out and log in. Is there something missing from an update? I don't mind switching with the terminal, but just wondered why I can no longer switch the way I used to do it.
