Turn on the File Name toggle on the Create Ad tab, and each ad is named after the file you upload, with the extension removed automatically: creative-black-friday.mp4 becomes an ad called creative-black-friday. If the ad set already uses the ADxx pattern, the system keeps the numbering by combining the two, for example AD20 - creative-black-friday. On the Ad with Instagram Link tab, the same option names the ad after the @username of the post's Instagram profile. While the toggle is on, the Ad Name field is disabled.
