Settings - URL shorteners
You can access these settings in the Settings application under the Social media -> URL shorteners category. In this section, you can adjust settings related to URL shortening services that can be set for Facebook, LinkedIn, and Twitter. Such services shorten URLs that are undesirably long in posts. Shortening is especially useful for Twitter posts because they cannot be longer than 280 characters and generated URLs can take up a lot of this space.
