From Support:
Thank you for contacting Webflow - Max here 
from the Support team. We appreciate you reaching out regarding your concerns with blog post
Currently Webflow sites meets the Open Graph protocol standards and tests we are conducting via tools like www.opengraph.xyz work as expected: Brix Agency Blog Open Graph and since we aren’t blocking LinkedIn’s requests to crawl this data, it appears to be an issue on LinkedIn’s end.
This could be because Linkedin has not currently implemented the latest version of TLS (Transportation Layer Security). Webflow runs TLS 1.3 as announced in August of 2022 and Linkedin is still running TLS 1.2. This is confirmed by comparing us with the site CDN77 a public TLS checker:
Firstly, I recommend reaching out to LinkedIn support for assistance if you have not done so already just to confirm there are not any issues originating from their end.
That being said your report is not the first we have received regarding this concern and we are currently monitoring this issue more broadly.
