Hello Hanna, I have had the same issue multiple times in the past with attempting to add a youtube video for music video to a blog post here on WA. My understanding is that you have to use the "Share" code and not the "Imbed" code when adding the link. That said, I have done that also and the video still will show up in the blog when I write it but it is gone when I publish the post. I have come to the conclusion that maybe there is some automated process here that removes links in posts (at least at times).

I Have been back and forth with Marion Black several times having her explain this process to me and she has been very helpful in doing so, but I still have never been able to get an actual video to show up in a post here (following the instructions to a T). I finally gave up on trying to add youtube videos in posts.

Also, I think if the purpose of adding the link is to get people to go to Youtube then it could be reported as spam.

I will look back here to see if someone else wiht more knowledge chimes in with a better explanation or if you get one, let me know as I would be interested in knowing as well.

Marion is helpful in this area and perhaps she will pop in here.

Thanks for the question.

I pasted the youtube link. It appeared in the post but after the post being published, the link does not appear, do I missed smt? i tried to edit and re paste the link.
