That is interesting. Out "standard operating procedure" for clients that have Meraki kit stolen is to create a new organisation for the stolen kit. We can then replace the stolen kit in the primary organisation with no licencing issues. And the stolen org used to prevent that kit from being claimed anywhere else.
It seems we'll need to go back and re-visit those stolen orgs, and create actual networks and put the kit into them, and then let licence violation kick in.
