New Plex Web release added signal strength, but can't seem to find it.

Looking at the release notes for 3.52.1 for PlexWeb, one of the features states:

3.52.1

NEW:

Added signal strength to channels in Live TV Setup and Manage Channels

I launched the Plex Web app via http://app.plex.tv and verified it's the latest version, however have checked both those areas and did not see anything. I tried with an existing WinTV Quad HD and adding a HDhomerun Extend. Can somebody show me where I should be seeing this?

Very excited for this feature, hoping in the future it will be something incorporated into the clients to see signal strength when viewing Live TV.
