Instance Created On field
In v3.25.0+ subscribed queues have a field referencing the instance the record was created on. This field will auto populate once a new record is created in the subscribe queues table.
This feature provides protection against cloned instances. The background job that subscribes to records from Perspectium's Integration Mesh for each queue will automatically check the instance created on field and deactivate any queues that were created on a different instance.
