Is a Delayed Recording Start Expected Behavior?

I am a first time Ring product user and I purchased a Ring Doorbell 2. I have it all set up and I've adjusted the motion sensitivity and the motion zones. I am currently running on battery power which I think limits recordings to roughly 30 seconds, which is fine. The one thing that is FAR from ideal is the fact that my recordings seem to start halfway through the motion. For example, a delivery driver will enter the camera view - quickly walk up, drop a package and then walk away. My recording/playback starts when the delivery person is walking away, completely missing the important piece....the subject's face and them walking up to my door. This doesn't seem to be a setting, this is extremely annoying, is this expected behavior? I anticipated a recording starting either slightly before or right at motion detection. I hope this can be resolved! Thank you in advance! Ryan
