How to import .sconn file in FortiClient VPN for Android?

In FortiClient 5.4.2 for Android, I can go to Settings, Import Configuration and I can successfully import a .conn file but .sconn (encrypted) files will not import for me.  It does prompt for a password when I choose the .sconn file, but it gives no indication that there is any error and nothing actually gets imported.  Has anyone been able to get this to work?

Thank you.
