Display & Video 360 doesn't support direct upload of expandable creatives, but you can sync them from Campaign Manager 360 or serve them from a supported third-party ad server then add them as third-party display ad tags.
When you add an expandable third-party display ad tag, you must set an expanding direction before it can serve. If the creative is built with Studio and served through Campaign Manager 360, the expanding direction is automatically detected.
Expandable creatives require manual review, which typically takes about 24 business hours.
