Auto Arm When Mobile Phone Is Not Present

I am really happy with my ring alarm system, but the one thing that is disappointing is that it does not have the auto arm feature that Auto Arms the system When Mobile Phone Is Not Present. Most other alarms have this option. I put in this request a few years ago when I actually communicated with Jamie Siminoff (founder of Ring) via email when he was actually responding to his customers personally. He thought it was a wonderful idea and he was going to look into it, and that was the last that I heard regarding this feature. Technically it’s a simple thing to do, I just don’t understand why it hasn’t been done already. It’s such an awesome feature!
