ArtStation has a Publish to LinkedIn feature, which enables you to share your work to LinkedIn and have it show up as a status update to people in your network.
LinkedIn classifies user posts into two separate categories, which can make it tricky to find your shared content
LinkedIn has 2 kinds of user posts:
Post - like a blog post
Activity update - like a Facebook post <---- ArtStation posts to this
ArtStation share works by posting to an activity update.
Click on "Profile" -> "Your Updates" to see the post.
It sometimes takes a minute to show up there.
