When attempting to monitor a network folder the following error is displayed when clicking "Test"

Folder Existence

Folder does not exist

I've attempted the following without success:

If I monitor a local folder and click the Test button I'm shown that the path being monitored is a network path and it's successful.  C:\Windows for example will be successful.

Is network share monitoring not supported in the same capacity as local folder monitoring or am I missing something?  Is there any documentation on this newly added feature for File and Folder monitoring?
