WhatsApp is testing a new feature which will allow users to “unsend” messages that they have sent to any of their contacts within a maximum time frame of five minutes. While there is no official confirmation, reports suggests that the new WhatsApp “message unsend” feature is being tested in a new beta version of WhatsApp Web.
In the beta version, WhatsApp has also made it easy for people to format text by providing options like Bold, Italic and Strikethrough. With this, you will no longer need to put asterisks, underscore or tildes to format chats. This update is expected to open to all very soon.
