YouTube Playlists not updating dynamically?

Is this with a phone app or store application?  I believe the phone application will look for an update on entering the application after it has been terminated.  There is also a refresh button in the application bar of the phone app which will refresh all the content, apart from static items, as long as there is a net connection.    

It's a Windows 8 app. Unfortunately there's no refresh button and no auto update with this version. You can check it out yourself, the app is in the store (for free) called Fail Videos.
