Google Home integration: getting "Simplisafe has a security restriction" response

I'm getting an error when I try to set Simplisafe via our Google home.  Google Home responds with: "Simplisafe has a security restriction." After doing more testing, it seems that it only works when the current Simplisafe setting is "OFF." If the current Simplisafe setting is "Home," it can't switch to "Away." And if it's "Away," it can't switch to "Home." The error is always "Simplisafe has a security restriction."
