Poor Customer Service- Smart Lock

I am really disappointed in the Ring Customer Service.I am trying to get the Ring Alarm to lock my door (assuming it is unlocked) when I enter 'Away' mode. I have these options selected in my app. However, upon testing, nothing happened. The poor customer service people said this isn't an option. Why would Ring enable this if it isn't an option?Also- just curious, assuming this app works as it is supposed to- why wouldn't I have the option to lock my doors when I use the 'Home' mode?
