WhatsApp is introducing a new 'safety overview' feature designed to protect users from group chat scams. Before joining a group chat with unfamiliar participants, users will now see a screen displaying information about the group, including its creation date, the inviter, and the number of members. The overview will also include a warning about potential scams and instructions on how to manage group chat invitations. Users can then choose to exit the group or view the chat. This feature expands upon the existing 'context card' functionality, providing additional security measures within the platform.
