Linked in share “remove your attachment to post from another account”

Hi there!

We have a bit of an issue whereby when the client tries to share a page via the linked in button and tries to share as a company, they are seeing the message “remove your attachment to post from another account. Go back”.

The options to share to different companies are greyed out, it looks like this.

I have got the client to submit a ticket with linkedin themselves to gain some insight but wondered if it was perhaps a known issue on the plugin side.

The page I need help with: [log in to see the link]
