Before importing an Ads Editor Share (AES) file with proposed changes, be sure you've downloaded the most recent version of the account. The import is likely to fail if your view of the account is older or newer than the exported version. Also note that files can only be imported into the account for which they were created.
Import an AES file
- Go to the Account menu > Import > From file…
- Select the file to import.
- Click Open.
