You are unable to deploy a policy Policy Deployment page of Apex Central as a Service, because the Deploy button is disable or grayed-out.
The issue happens if the user account currently logged-on is not the owner of the policy that is being deployed.
There are two options to fix the issue:
- You can use the Policy Management screen to change the owner of a policy to another Apex Central as a Service user account:

When you change the owner of a policy, Apex Central as a Service sends an email notification to all user accounts assigned the "Administrator" role.
