It seems Lenoovo and the Forum don't have a solution. The store I bought it from has the answwer. When the Dock is connected to the Yoga by Thunderbolt cable, it puts an icon on the bottom task bar, right side. The icon went into the overflow box with other HIDDEN icons. /\ symbol opens the HIDDEN icons. You have to click on the Thunderbolt icon and activate it, then allow it to make changes to your Yoga. You can drag and drop any of the HIDDEN icons to the bottom task bar where you can see them. I hope this helps the other person who said they had the same issue.
