At the Advertiser level, when creating or editing a Creative > Flight, the End Date field is now optional.

When no end date is selected, the creative flight will remain active indefinitely. When an end date is selected, the creative flight will continue to follow the existing end-date behavior and will become inactive once that date is reached.

This update helps prevent creatives from becoming inactive when a campaign or line is extended beyond the original creative flight end date.
