How to get the Bravia component to show apps?

Having looked at the Bravia Component it should be able to know when you’re playing content using an App and be able to select that app in the sources list. But in sources I only see the HDMI ports (no DTV channels loaded as no aerial)

It just Says “App” rather than any other detail on the card

And on the media_player info it shows it as “App”

volume_level: 0.26
is_volume_muted: false
media_content_id: App
media_title: App
source_list: HDMI 1,HDMI 2,HDMI 3,HDMI 4/ARC
friendly_name: Office TV
supported_features: 19901

Am I missing something?
