Forgot to update, but after a couple of days, the email support team was able to restore a lot of my setup. Still had to put stuff in rooms again, and lost some devices. But it was much more manageable.
Amazon Echo was a pain to get set back up because it wouldn’t discover the devices that moved back to the location with all th automations. Had to disconnect SmartThings and reconnect/discover several times to finally get it to work.
On the other hand, Google Home was simple to get the devices back into a controllable state.
