Yes. The editor works in Publication Queue Mode: when you click Create Ads, your files upload to the server in seconds and publishing continues in the background, even if you leave the page or close the browser. When you come back, the system automatically restores the job in progress and shows the real status of each ad (published, failed, or still processing). When it finishes, you also get an in-app notification with the number of ads published successfully. This applies to file uploads and to Ad with Instagram Link mode.
