Can't answer doorbell in time

HI,I have the original ring doorbell and the app on my Iphone. I'm finding that when someone is at the door, by the time I find my phone, open the app, and press a couple of buttons to get to the answer page the person has left the front door thinking no-one is home.This is very frustrating and making the product worthless - does anyone know how to speed up the answer process?
