Sharing image on Linkedin

Hi there,
It seems since sometimes, the linkedin Share button doesn’t allow to share the “A la une Image”, nor image put in meta-tag FB by plugin yoast seo.
Even when I put url of article wp directly on Linkedin post, no one image appears.
EG with this article : https://www.bdgassurfinance.be/transition-vers-nouvelle-mobilite-urbaine-v/
An idea of problem ?
Thks a lot !
