Bug report: Light schedule stopped working

Hi,My light schedule has stopped working. It was working fine for weeks but it has stopped working over the last couple of days. I've gone into the app to enter a new light schedule but it rememberd my old one, so I just clicked save. Going back into the light schedule, I see that the option is enabled but in a light blue colour instead of a dark blue colour.Is anyone else experiencing this? Is there a fix?Thanks
