How does inheriting the previous ad's settings work when uploading creatives?

When you upload an ad in Meta Ads Editor and leave the URL, headline, and primary text fields blank, Ads Editor automatically copies that information from the last ad in the ad set, including the linked Instagram account.

1. Drag the creative into Meta Ads Editor.
2. Leave the URL, headline, and text empty.
3. Click Create ad.

This way you only swap the creative and keep everything else the same, with nothing to reconfigure. To override a value, fill in that field before creating.
