Same problem I’m having. I’m trying to move some of my time to less peak times to see if it helps. I even got to the point where I created backup timers to double check if the lights turned on but last night even my backup failed. And then there’s the app that executes the command but the device never receives the on/off command. It’s just a mess.
Check your app schedule and see if the next execution date maybe have lapsed already, in that case it will never fire until you edit and save it again.
