When using StageNow xml Config scripts in packages I sometimes get this error:
Script command is not supported by device (xmlconfig)

Sometimes I don't get this error and it processes correctly.

Most of the time when I get the error the changes still go into effect so the XMLCONFIG must be processed.  Other times it does not and I have to remove and re-add the package to get the StageNow profile to take.  Is there a reason this is happening?  It works most of the time, but there is no good way for me to know when it doesn't work and I get devices out in the field that are not fully setup.

My package has a simple TimeZone (Clock) setting from StageNow, and the script command is "mxconfig /sdcard/TimeZone_Eastern.xml".  The devices are Zebra TC70X and they are running Agent version 13.7.0.1031 on the devices.
