Quick answer
If a LinkedIn post shows no button, paste the exact public video post URL again and check that it opens outside a private session.
On LinkedIn, a post can look like a video post while still failing to expose a usable downloadable stream. The post type and pasted URL matter.
Why the button can be missing
The post may be public but still not expose a direct public media stream, or the pasted URL may target the feed instead of the exact video post.
- Copy the exact video post URL.
- Test the URL while logged out.
- Network-restricted content will not work.
What to verify on LinkedIn
A true public video post page is the best case. Feed previews and internal group content do not always expose usable media.
- Avoid internal feed links.
- Use the full post URL.
