Title-Level Publishing Windows
All Screeners within a title are subject to the launch and expiration dates set at the title-level.
When creating a title, dates are an optional field which can be left blank. However, if dates are set, those publish and un-publish dates will override the "viewable" status marker on the Screener, and can be used to prepare the Screeners to automatically publish at a set date and time. This can be set down to a half-hour window:
If a time is not selected, the selected date will take effect at 12:01am in the time zone of your device.
