messenger 18.1.1 send file

I just updated my messenger system to 18.1.1 (from the last version of messenger 3).  Users quickly discovered the new "Send File" option which is available in the client under "Actions" and tried to use it.  It just returns an error code 0xd10a.

Send File is not supposed to work yet I know, but why is it enabled in the client?  The gwadmin console profile setting for it is unchecked and greyed out so I can't change it.
