Facebook Messenger now has a feature that allows you to unsend a message.
The feature is not something that’s new, as WhatsApp already gives users an option to unsend messages. On Facebook Messenger, a user is given up to 10 minutes to delete a message after they’ve hit the send button. You will get an option either to ‘remove for you’ or ‘remove for everyone’. And similar to WhatsApp, when the message is deleted it will leave a stamp to show the message was deleted.
The feature is now live for Android and iOS devices.
