Problem: When a new machine joins the organization/machine group, the policy is not getting assigned.
Resolution: Make sure that the view that is assigned to the policy is associated with the machine.
If it is, go to Policy-->Settings and make sure that you have a deployment interval set
If you do, please toggle the interval, meaning if the interval was set to 5 minutes, change it to 10 minutes and go back to 5 minutes. If you are still having issues, please remove the policy from the organization/machine group and reapply it again.
If you continue to have issues, please create a Support Ticket.
