My cams and thermostat were not responding to SmartThings Classic app control. Even though the SmartThings app showed my cams streaming, they were not. So I removed the devices and logged my Nest account out from the NST Manager and back in. My Nest Cams and thermostat were rediscovered and responding to SmartThings control.

However, the old scenes that I had created using the originally discovered Nest devices can't be edited or removed. Attempting to edit the scene gives me error saying "Something is wrong. We can't load your screen right now." only a Retry button is available to try loading the screen again. There's no way to remove this scene.

Other scenes that do not reference the originally discovered Nest devices load fine. How do I get rid of these zombie scenes. I can create new scenes to reference the newly discovered Nest devices, but I don't want these dead scenes laying around.

I tried the newer SmartThings (Samsung Connect) app, the zombie scenes don't show up there. 😕
