Having the exact same issue. It was working fine, and a couple of weeks ago the posts stopped showing up on my feed. I haven’t updated to wordpress 5 yet.
The posts are sent to linkedin: https://www.linkedin.com/feed/update/urn:li:activity:6486210198649257984/ but it doesn’t appear on my feed: https://www.linkedin.com/company/red-del-petr%C3%B3leo/
My settings:
PHP Version: 5.4.45
Wordpress Version: 4.9.9
Plugin Version: 6.15
