If a Vimeo video in your publication stops displaying or no longer works for readers, the cause is usually a missing privacy access token in the video URL.
A privacy access token is a unique string appended to a Vimeo URL that controls access for a specific audience. Example: https://vimeo.com/648927264/b475c80847 — the bold part is the token.
To retrieve the token and update your publication:
In Vimeo, click the Share link button on your video and copy the URL.
Go to the embedding settings for your video and copy the privacy token — it appears after "h=" in the embed code.
Append the token to your video URL with a / separator, then copy the full link.
In your Joomag publication, go to editing mode, click the Vimeo icon to replace the broken video, and paste the updated link.
