Note that the preview starts on the TV app landing page, so you may need to navigate to the required rails using the TV app navigation.


You can select options in the sidebar to:

  • Preview how a layout will look on any future date and time

  • Preview how a layout will look to different target segments and variants that are part of a segment targeting experiment

When you have made your selections, click Update Preview.
