Ring pro person detection

So this is my 2nd replacement ring pro. Peraon detection often does not work...the infrared lights do not always come on. Just installed the replacement...waited for the update...set up person and package detection...motuon detection but no person detection, no infrared lights. Ok, we tried shutting off the outdoor lights. Aha the infrared comes on, person detection! Turn the lights back on, infrared stays on! Ok a delay somewhere. Walk out onto the porch, no motion detection no person detection.
