Last Seen is a feature in WhatsApp that allows users to see the last time a contact was online. This can be useful for knowing when someone was last active on the app, or for checking if they are currently available to chat.
To see someone’s Last Seen, open their chat window and look below their name. You will see a timestamp indicating the last time they were online. If the Last Seen is not visible, it means that the contact has disabled this feature in their privacy settings.
