Try replacing @math with this. It would cause a match on any Linkedin page, but if it works you can just toggle it. I have not tested the script with this, I just randomly saw your post. Also, remove the quotes....just in case.
"// @match *://linkedin.com/in/*"
The script still doesn't work on the latest profile views page https://www.linkedin.com/analytics/profile-views/
Seems like the URL has changed and this script no longer works. Changing @match doesn't fix it.
