Brian,

Thanks, for your help guys.  See my results below.

Here are my results.  I'm running on an ssh termial and I find I have to
'su app' to run your command.

ls -lZ shows.

drwxrwxrwx 2 app app _ 4096 Apr 10 12:59 Camera
drwxrwxrwx 2 app app _ 4096 Apr 10 12:59 Downloads
drwxrwxrwx 2 app app _ 4096 Apr 22 17:40 Images
drwxrwxrwx 3 app app _ 4096 Apr 22 17:40 Sounds
drwxrwxrwx 2 app app _ 4096 Apr 10 12:59 Videos

I ran the command 'chsmack –a User /opt/usr/media/Downloads'

ls -lZ shows.

drwxrwxrwx 2 app app _ 4096 Apr 10 12:59 Camera
drwxrwxrwx 2 app app _ 4096 Apr 10 12:59 Downloads
drwxrwxrwx 2 app app _ 4096 Apr 22 17:40 Images
drwxrwxrwx 3 app app _ 4096 Apr 22 17:40 Sounds
drwxrwxrwx 2 app app _ 4096 Apr 10 12:59 Videos

No, Net change.  I'll try again just to see.  After running the app.  I get
these results from 'journalctl -f'.
