I’m having an issues with devices showing as unavailable in the new Smartthings app. The device continues to function just fine. Routines work. Google home works for both routines and controlling the device directly. And I can access the device in Smartthings Classic just fine. But I can’t access or control the drive directly in the new Smartthings app, nor can I modify the device in any of the routines to which it is assigned or add it to new routines.
The device is a leviton z-wave plus dimmer. I have 30+ of these devices in the house. Half a dozen are exhibiting this behavior. Within the same doubl- gang box, one will be connected and the other will show as disconnected or unavailable.
