cross-site tracking cookies enabled despite `dnt=1`

I haven't found a fix for the issue described below but I believe this is a bug with dnt=1.

Discussed in https://github.com/vimeo/player.js/discussions/889

^{Originally posted by tvercaut January 24, 2023} Hi,

I am trying to embed a vimeo histed video in a webpage without needing an opt-in cookie policy. I understood that the "do not track", dnt=1 parameter was designed for that purpose: https://complianz.io/embedding-vimeo-videos-privacy-friendly/

However, firefox reports that the vimeo player makes use of cross-site tracking cookies despite the DoNotTrack request. As one can see on https://complianz.io/embedding-vimeo-videos-privacy-friendly/ when the browser is configured to block cross-site tracking, the console reports the following:

Request to access cookie or storage on “https://player.vimeo.com/video/643915247?title=0&byline=0&portrait=0&badge=0&quality=1080p&dnt=1” was blocked because it came from a tracker and content blocking is enabled.

Am I misunderstanding the dnt=1` parameter or is there something else that needs to be done to prevent vimeo from requesting such cross-site tracking cookies.

Many thanks, Tom

I have also been having issues with dnt not working. I can clearly see it in my URL, as ?dnt=1 but Vimeo cookies are still appearing on my site. More info on this would be great.

Closing this issue in favor of the existing discussion because this is not an API or API library issue.
