i posted a video from YouTube, with the link is coming a preview, but it is just grey.
its telling me to login (on Yt?) to see the video. in YT, it is public, normal like always.
What is to do?
Since you're obviously not willing to provide further details
we can't help but will have to close this case.
you were talking about a youtube video link you were trying to post,
that's why I was asking for the youtube video link, not a site link.
So please provide exactly that youtube video link you were trying to post
its a post inside my sozial media, can you see it from outsiede?
