It seems that when you post the url for the VRChat world on X (Twitter), the link is not working properly under certain conditions.
If the world's web site has a video thumbnail as an introduction, clicking on the link posted on X will play the video, but will not take you to the world's page.
This phenomenon seems to have occurred after the recent change in the specification for pasting URLs in X.
The same phenomenon occurs when I click on a link in a past post, not a newly posted one.
I am not sure if this is a problem that can be addressed on the VRChat side, but I would appreciate a fix.
