Recently all my Floodlight Pros turn on without motion (and stay on)?

I noticed about 2 days ago all 4 of my Floodlight Pros turn on and stay on without any motion. I will manually go into the app and turn them off and then will notice that within an hour they’ll all turn on again, and stay on. They all usually turn on around the same time and will stay on until manually turned off. Granted it’s been colder (40 degrees) in the last couple of evenings, but does anyone have any ideas what could have caused this? A possible firmware/software app update maybe? I know the sensors couldn’t have all gone bad at the same time in all 4 lights. I’ve rebooted each device and the RSSI is green for all 4 Floodlight Pros.
