Can't load PDF via OneDrive - Hangs on 'Downloading...'

We're having the same trouble with all our Surface Hubs. Here's some more info:

1. When opening a program, using the File -> Open command of that app, and selecting OneDrive, navigating and opening a file, it says that it has downloaded the file, it doesn't open directly from OneDrive. The download is to the AppData folder, so when you try to simply save, it fails because it doesn't have permission to the AppData path and forces a Save As command. The Save As allows you to go to OneDrive and save, but only as a new file, no overriding works, and each consecutive save causes a " 1" to be appended to the file name, making lots of fun duplicates of that one file.
2. If you open OneDrive, download to a local acceptable location (documents, downloads), and work on the file, it works perfectly fine, with no duplicates. But now you must remember to save as to OneDrive before your session is ended, or else you lose the work altogether.

Seems like the OS on the Surface Hub should have seamless file management between the apps and OneDrive as a file location, with the consideration of SSO being established with the device.
