X (Twitter) is currently experiencing an issue where live streams do not automatically become a post on your profile.
We anticipate that X will fix this issue at some point. Meanwhile, you can post the live stream in your profile manually:
One the broadcast has begun, press ⌘-F, or choose View Post on X from the Ecamm menu at the top of the screen beside the menu.
Your X live stream will open in your Mac's default web browser.
Click the
(share) button in the bottom-right corner of the stream.
Click the Post This button.
Click Post.
