Synchronization not working on TV + videos

Context

I have a Philips Google TV and a Philips Hue Bridge (Pro). I purchased the Philips Hue Sync / Essential Premium pack that is accessible directly from Philips Google TV.

What works correctly

  • Hue lights synchronize properly:

    • In the Google TV interface (menus, browsing)
    • On YouTube videos
    • When launching streaming apps such as Disney+ and Prime Video but only during advertisement videos

What does not work

  • On Prime Video and Disney+, the main content does not synchronize with Hue lights:

    • The Hue Sync icon is red (indicating an active sync session)
    • Only advertisement videos trigger light synchronization
  • Live TV / TV apps do not synchronize at all:

    • The Hue Sync icon is red
    • No light synchronization occurs under any circumstances
