Just purchased a PETKIT Puramax 2. It’s been a week and I decided to install the smart spray with the light and the light doesn’t come on?

It illuminated when I put batteries in and illuminated when I put my hand in front of it. But when installed it it has never turned on when my cats enter. It says through the app that’s it’s connected but I don’t see any settings I can change for frequency or light or anything… any help?
