@Ashok - I even created new rules for sunlight and sundown. While it appears that the rules will be saved, what really happens is the app sits there for a while, then pops back to the rules page. When I select the rule I just created, there are no sunlight or sundown widgets that I had just put in and tried to save.
I've also recently noticed on several occasions that on several rules that are off are somehow manipulating devices on, or rules that are on are not working. Thus bulbs are on far longer than anticipated, or not turning on when they are supposed to.
It used to work great! It would be awesome to get it back to that point!
