Preview a layout

You can use preview mode to help you to visualise how layouts will look in the TV app, based on their active and scheduled dates/times. This is particularly useful when you’ve created a new template, made changes to an existing one, or if any layouts are part of an experiment.


To preview a layout, click the Preview button (eye icon) at the top right of the Templates screen.
