I just made a post with a movie trailer in it. I chose to "Copy Link", and what was copied was the video description instead of a link.
Also, the Magnet URI for the video does not load anything on the airshare site.
Magnet works fine for me now too. It did not right after I uploaded, and timing probably had something to do with it.
Magnet URL worked fine for me on your post. And the "Copy Link" does nothing for me
