{url} not appearing on Facebook

We are using the free version. The {url} parameter on the default status is not getting shared across to Buffer for the Facebook accounts, it works fine on Twitter accounts though (even shortening the link).

Also, we want to add an emoji to this default status, but whenever I click ‘save’ the emoji is discarded and not saved.

We would like to have both the emoji included in the status as well as the url being fed to all social channels (we currently only have FB and TW linked).

Any help resolving these issues?

Thank you in advance.

Wordpress version: 5.2.2
WP to Buffer version: 3.5.3
