I have a new description in the page but when I share the page it is still using the old description that no longer exists, I am after something similar like the Facebook Lint.
Any ideas?
You can append dummy query string value to your url and make it look like a new url and LinkedIn fetches it again. I've tried it and it works.
For example:
https://www.codeproof.com/?refid=LinkedIn
where refid=LinkedIn is just a dummy value.
If your url already contains query string and then just append "&refid=LinkedIn" at the end of the url.
