Trying to download previous PS CC version. Why can't I see "previous versions" in CC app?

I'd like to download the previous version of Photoshop CC (currently have PS CC 2014). I have tried the help document explaining how to use the desktop CC app and look at the "previous versions". My app does not include previous versions though. I have tried re-installing Creative Cloud and saw the same issue.

Screenshot shows my app on the left which just lists new apps to try and the right is from the help document.
