Thumbnail Not Appearing in Shared Link or Loading Screen

Report · May 14, 2025

Hi Adobe team,

I'm creating a series of AR experiences in Adobe Aero and have encountered a consistent issue with thumbnails:

Problem:

Even after correctly uploading a custom thumbnail image (JPG, 2000×2667, <1MB) via the Share > Thumbnail panel and clicking “Apply Changes”, the thumbnail:

• Does not appear on the public share link preview (https://adobeaero.app.link/...)

• Does not show up on the white “Loading…” screen when the link is opened on mobile (iPhone)

• Does not display when the link is pasted into platforms like Viber or opened in an incognito browser

What I’ve Tried:

• Uploaded the thumbnail multiple times and clicked “Apply Changes”

• Created a brand new share link by duplicating the Aero project

• Tried different JPGs, resolutions, and names

• Tested in incognito browsers and multiple apps (Telegram, Safari, etc.)

• Even used external debuggers (Facebook Sharing Debugger) — confirms no metadata is embedded

What Does Work:

• The AR experience loads and runs perfectly otherwise

Request:

Can you confirm:

• If this is a known issue with the Aero share system?

• Whether thumbnails are currently supported for aero.app.link previews?

• If there is a workaround (e.g., setting metadata via another platform)?

• Whether a future update will allow reliable thumbnail previews for shared links?

Thanks in advance.

I have also had this problem. It even effects projects that I had compleated a while ago in which the thumbnail displayed with no issues.
