Facebook-owned messaging giant was testing disappearing or self-destructing messages for Group Chats. The platform’s sister app, Facebook Messenger, has had the functionality for some time within its so-called “secret conversations,”, meaning they’re end-to-end encrypted.WhatsApp is stepping up plans to launch the functionality some time soon.The app versions are 2.20.83 and 2.20.84 and you can choose the expiry period of the messages between one hour, one day, one week, one month or one yearWith a timer set, users can see a clock icon which warns them that the message will disappear, providing an indication of how long remains. There is no confirmation as to the timing of the launch of the new functionality, or whether other security protections such as reporting screenshots or preventing text-copying will be added as part of this shift to more secure endpoint functionality.
