Chime Pro nightlight toggle switch won’t stay on

I recently installed a door bell and Chime Pro, where installation and connection went fine. However, the nightlight on the ChimePro stays on constantly and when I go to Ring app and try to toggle the nightlight switch, it slides on but then automatically slides off again. I get the message from the app that the light will now only go on when dark but the light remains on and stays on no matter how bright the room becomes. Has anyone come across this issue and been able to resolve it? Thanks!
