There are several different reasons why the bookmark folder might not appear.
1. Make sure you are logged into the chrome browser. You can check this by going to settings within the Chrome browser and selecting the You and Google menu from the left panel.
2. If your MPS Google Account is listed in the You and Google setting area, you will want to verify that syncing is turned on. If you see a turn on button to the right of your name on the above screen, your account is not syncing.
