问题
Posts made via the Share on LinkedIn API for users on the new user interface appear on their accounts with at most: a user message/comment, image, title, and link domain. However, the documentation on the Share on LinkedIn API (https://developer.linkedin.com/docs/share-on-linkedin) describes that the request body can also contain a "description" field with text up to 256 characters. When the description and all the post fields are provided explicitly to the API (as in the example in the documentation), the description field does not appear for users on the new UI. The description field did appear for users when they were on the old UI.
The Share on LinkedIn API provides an additional option for sharing by omitting the post details fields (title, image, description), and allowing LinkedIn to generate the post based on the Open Graph data it finds at the link URL. However, the result is the same as above for users on the new UI.
Is this a bug, or is the documentation out-of-date?
