Since our initial communication, Twitter decided, on short notice, to dramatically change the terms and pricing of the Twitter API. We have attempted to work with Twitter in good faith to negotiate new terms, but we have not been able to reach an agreement. As a result, we will need to remove the functionality.
When Twitter removes access on April 30, 2023, your Twitter connection on Jetpack Social will cease to work, and your blog posts will no longer be auto-shared to Twitter.
You will still be able to share your posts to Twitter manually by pasting the post link into the body of your tweet.
In addition, you can still auto-share your posts to Tumblr, Facebook, and LinkedIn. In the near future, we are adding the ability to auto-share to Instagram and Mastodon. We are continuing to release new features in Jetpack Social, so keep an eye on the Jetpack blog for more updates.
We’re truly sorry we can’t continue to support Twitter in Jetpack Social. Please feel free to contact us if you would like assistance.
