LinkedIn and Twitter have worked together since 2009 to enable the sharing of professional conversations on both platforms. Since this relationship began, some of you chose to sync your LinkedIn and Twitter accounts to share your professional content, knowledge and expertise.
Twitter Team director Michael Sippey said they are increasingly focused on “providing the core Twitter consumption experience through a consistent set of products and tools.”
"Consistent with Twitter's evolving platform efforts, Tweets will no longer be displayed on LinkedIn starting later today,"
Connection from Twitter isn't completely lost, though LinkedIn users can still updates to Twitter via the "Share" button, which will update LinkedIn connections and Twitter followers.
Changes On LinkedIn :-
If you had previously synced your LinkedIn and Twitter accounts, and selected the option to share Tweets on LinkedIn, those Tweets generated from Twitter will no longer appear on LinkedIn. There will be no other changes to your LinkedIn experience.
Professional conversations are happening every day on LinkedIn, and we encourage you to take part in these dialogues. If you have any further questions about what this means for your synced LinkedIn and Twitter accounts, please visit our Help Center.
