What does it mean on Facebook when it says you're not connected?

When Facebook indicates that you're "not connected," it typically means that you and the other user are not friends on the platform or that the other user has restricted their privacy settings, preventing you from seeing their profile or content. This status can limit your ability to interact with their posts, send them messages, or view their photos and updates. Essentially, it signifies a lack of mutual access to each other's profiles.
