Floodlight schedule not working

We have had a problem with our floodlight for over a month. I've even spoken to a customer tech at Ring. We have the lights scheduled to come on at 5 pm, turn off at 7 am. The lights will turn on at 4 pm, shut off at 6 am. We've adjusted the time in the app, saved it and it still does not work. We've reset the light according to the Ring representative, reset it through the wired switch and have even removed the app from our phones and then added it again. I'm not sure if there's a problem with the light/camera or if there's a problem with the app, which my husband thinks. We have had this camera/light for a year and never had a problem before.
