Delay when doorbell activates lights via bridge and transformer

My alarm and Pro 2 doorbell have been working well for a good while. Added a bridge, motion detector and transformer for path lighting.When triggered by the motion detector, the lights come on nearly instantly. When triggered by the doorbell however, there is a delay before the light comes on. I enabled Motion Alerts, and I'm notified the doorbell has detected motion almost immediately, but there is a delay between 10 seconds and a minute or so before the lights come on. Basically enough time that you have to stop and wait on the lights before continuing to walk.Any ideas how to get a faster response?
