Ring Alert Notification - Motion at your home

Can anyone answer this...I get an alert on my phone that there is motion at my house. I go into the app or simply click the notification and it will say Activating Device. It says this for a while too. If someone was really at my house up to no good, I wouldn't see them right away. Even when I tap "Go Live" there is a long delay with that as well. My question is why is it taking so long before I see something? I do see it say processessing. I also noticed a delay when someone actually rang the doorbell. I heard the doorbell chime in my house before I got the alert on my phone. My WiFi signal is strong. I am just wondering why I am getting these delays.Thanks
