Ring Flood light cam light not working!

I too am having trouble with the time on/time off, on one of my floodlight cams. When I set the schedule for the floodlight to come on, it works for a day or two then it stops working. Both of my other floodlight cams are working fine, according to the schedule I set them up for. It’s only this one that doesn’t want to comply with the schedule I set up.

I’ve heard from some people that Ring uses GMT, which is five hours ahead of EST. As I type this the clock in the blue bar above says it’s "Autosaved at 7:58 PM. It’s 10:58 PM here. So why is the clock showing a three hour difference instead of five hours.

And by the way, I would like to solve the floodlight issue.
