I have a very similar situation.
After opening the new app, everything got messed up. My current status is as follows:
-About half of my devices AND my HUB have moved to a new location
-The other half of devices and all automations/apps stayed in original location.
So my questions are:
-With Classic app or IDE is there a way to move my HUB to the original location?
-With Classic app or IDE is there a way to move devices from one location to another?
