Is ST up right now? I cannot turn on/off lights from the app, nor does the status of a switch change when I manually tun on/off the switch. Also, I see that my outdoor lights are clearly off, which means the routine ran at 1:15 am , yet the app shows the lights are on and the history stops at 7:51 pm last night when they turned on.
The Smartthings status website says everything is operational in North America!
One more note, I am having the same problem with a second hub in a different location, so I know it’s not my home hub.
