Floodlight cam lights won't go off.

Posting on behalf of my father. He has just set up a floodlight camera at the front of his house, he already has one at the rear.Got it all installed on the wall and went through set up, got it connected to the chime pro we are using for the rear floodlight camera. The problem is that the floodlights on the front camera will not switch off. I have selected the lights off in the ring app but the lights are still on, thought it might be the motion sensor being to sensitive so turned it all the way to it's lowest setting ans still the lights will not go off. Have had to switch off the whole unit until we can get this resolved.
