I moved automations moved off of the “Smart Lights” App and into the new SmartThings app for half a year now. I have never had any issues.
In the past week or so, something has changed. My automations fire as expected, but when I have the option for the light to turn off automatically after X amount of time, The lights never turn off.
This happens for all my automations, not just a single one. I reached out to ST support and they haven’t provided anything useful. None of these automations write to the IDE logs, at this point I am really just curious to find out if I am the only seeing this issue.
