No "Sites" listed in Open section of the Document Gallery

Hi All,

 

At my company, we're seeing an issue where we don't see the Sites listed in the Open dialog section of the Document Gallery as shown in the "What's New" list for January 2018:

 

 

 

 

 

 

 

We're running Office 2016 apps v. 16.10, and are connected to Office 365 Online.

 

However, if I connect to my company's Office 365 account from my personal computer (using the same version of desktop apps), it shows the Sites. This inconsistent behavior is making it a bit difficult for us to train teams on how easy it is to get to their Group documents from within the desktop apps.

 

Has anyone else seen this issue?
