Add private Vimeo-Links didn't work
If i add an private Vimeo-Link (e.g. only for special websites, etc.) on a content element (add media url) TYPO3 removes the last part of the url. It results in an non-working vimeo file.
Maybe this blog post could help u https://vimeo.com/blog/post/share-unlisted-videos-with-private-links
