Ok. Found the cause of the SOS issue.  
It was the immediate call to Spark.process() after Spark.connect(). Please remove the process() call within the if(){ } and it should work.  
I’m going to add a check for the cloud socket in Spark.process() to prevent this bug in future firmware release.  
Thanks for pointing out the issue.
