Floodlight plus motion lights not working

Hi. I recently purchased and installed hard-wired floodlight plus. I double checked the settings in the app, motion-activated lights is turned on. But when I approach towards the camera and get within the proximity, lights won’t turn on. Only way I can turn on the lights is to toggle the lights on, and push the button on the camera. But I will also have to turn off thru the app to actually turn off the lights. Anything I’m doing wrong? All the settings seem to be correct. Thank you
