Is PlayOn Cloud Integration Still Functional?

The Channels website (Channels Support - PlayOn Cloud) doesn't indicate the PlayOn Cloud has been eliminated, but when I start to add a new source, PlayOn is not offered as an option (just HDHR, TVE, and Custom Channels).

Do I need to do anything before adding a new source to enable the system?

It's under the Personal Media section.
