Why the share preview shows old text or image

Messenger, Zalo, LINE, and other apps often cache link previews. If you edit names, dates, or cover photos after sharing, the old preview can remain visible for a while.

The invitation itself updates faster than the preview. Open the link directly to confirm the page content is correct.

If a preview is important, use the app's preview debugger when available, or wait and resend the link in a new message. Publishing changes before the first large share usually avoids this issue.
