Just got the new Spark 16 sprinkler controller and installed it yesterday.  I'm trying to add "New Manager" in the app (& tried it on the website too), but keep getting this error message:  "ERROR:  Can't find user [email]"   (I've omitted the specific email address of the manager/player I'm trying to add and simply used [email] as a placeholder for this thread)

I've also tried to add "New Player" and get the same error message.  

Has anyone else had this issue?  Am I doing it wrong?
