Download failed

It happens sometimes when content have been created with elements (shapes, icons, stock photo & videos) that are no longer available on the platform. For example in the case of a photo, the original creator may have decided they no longer want their photos distributed on Adobe Stock (it's where the photos, videos, icons and music comes from)

Now what you can do is identify the element that cause an issue, delete it (so it will be trial and error) and try to download. Youu can still replace it with something else once you have identified the culprit.
