WhatsApp rolls out 'delete for everyone' message feature

WhatsApp is slowly rolling out a new feature that allows users to revoke or delete a message within seven minutes after it has been sent so that the receiver won't be able to read it - if both parties have the latest version of the app.
How it works:
Users with the latest version of Whatsapp will see a new option after sending a message that will allow them to “delete for everyone” instead of just from the sender's own device.
- Tap and hold the message
- Choose 'delete' from the menu options
- Tap 'delete' or the trash can icon
- Choose 'delete for everyone'.
