Started with a free Dropbox account that I setup an App for and was able to generate manual auth tokens to access it using the Dropbox .Net API. Everything worked as expected with App API "Root" access being the topmost folder.
Then a paid Dropbox account was setup and I was invited to join that paid account. My original "Free App" for token auth and API usage was brought along plus a new App was setup with Full Dropbox access:

No matter which App I use (the previous free App or the new Full Dropbox access App), when I generate a token manually under that app, my default user folder is always treated as "root" as circled below:

How do I access other folders that I have access to in the Dropbox web UI (pictured below) when my root is always my topmost user folder?

Again, I tested with an auth token that had Full Dropbox App Scope and Access.
