I am not sure if something strange has happened since the update but I have a time variable set in my "main bedroom" dashboard. I could edit the time, lets say 6am, and then hubitat will start turning the lights on slowly in my bedroom based on that time. I can change it to 7am and it'll do that. But that functionality has stopped working. I checked on my desktop and that icon has disappeared. I tried to make a new icon in the dashboard and it doesn't work anymore. Did I miss something that it was it removed?
do you have a connector on the variable?
what firmware are you running on your hub?
Check out this thread. I think it’s the same thing.
