OneNote issue with Share button

Hello all,

We are having an issue when trying to use the Share button in the Windows Store (UWP) version of OneNote. When a user clicks the Share button this dialogue box appears after several seconds:

I've tried as well and have the same problem. Annoyingly, it does occasionally work and the normal sharing dialogue appears 

I've updated OneNote and the version (I assume this is the latest) is 16001.12325.20040.0

The Notebooks are stored in either a users OneDrive for Business or on a SharePoint site. The web app Share button works fine.

Does anybody have any ideas on what is going on here?

Best wishes,

Steven.
