As you can see above, the status is set to "disabled" with a red icon, and the button in the top right has changed color and is set to "Enable entitlement," ready for you to reverse the process when required.
The entitlement "disabled" status can also be seen in the list of all your entitlements.
The status will now show as "created" where it was before it was changed. The red disable button shows again for any future changes.
The entitlement is now fully activated again, and the activation codes attached will function again.
Note: Entitlements can be disabled independently of the customer being disabled, which means that you can disable one or the other, but the entitlement will remain disabled if you set it here, even if the customer is re-enabled, etc., i.e., if you disable an entitlement, you have to re-enable it directly not via the customer process.
