Publicize sharing preview urls

Jetpack’s Publicize does indeed use shortlinks, and not full permalinks.

If you’d like to change the shortlinks on your site, you can use a plugin like bitly or yourls to generate short urls for each one of your posts, or follow the instructions here to replace shortlinks by full permalinks:

Hi Jeremy,
That’s a big issue. Thank you for responding.
