Webetainfo, a twitter account that tastes WhatsApp updates before they are endorsed announced that delete for everyone is in the final stages of testing and will be made available soon
WhatsApp is finally testing the Delete for Everyone feature: The server finally works and it successfully recalls the message’Also if the server works, this does not mean that the feature is currently enabled. It will be remotely enabled later, and seen that WhatsApp ‘enabled’ their servers for the Delete for Everyone feature, it may really be enabled soon,” according to Webetainfo
Meanwhile the delete option will only be available five minutes after sending the said message. Once the reader has already received the message, you will not be able to delete it. It will be available for all forms of messages, from images to voice notes
