I migrated my classic Smartthings into the new Smartthings app and have noticed one thing that I relied on for trouble shooting in the classic app that isn’t in the new app. Detailed history in the classic app. It would tell me what webcore piston, routine, or command triggered what, and various other info. With the new app all it lists is on or off and the time.
The detailed history should have made the port over to the new app. I like being able to look at the detailed history and figure out if something went wrong, or what turned something on or off.
I hope they plan on bringing this over into the new Smartthings app soon.
