Yes, you can you not see what SmartApps are using a specific device. Not only that, but in the history view you can’t tell what SmartApp acted upon the device. It makes it impossible to figure out what turned on a lamp when you have multiple SmartLighting rules that can act on it.
E.g., this light can be turned on by motion or by the door opening. The Classic app shows the SmartApp (motion or door opens) and show the commands (on, setlevel, etc). The new app hides all the helpful details.
(and as I’ve noted before, the history view in the Classic app kept the date it was showing at the top (“Today” in the screenshot); the new app doesn’t!)
