In its ability, Facebook tested this cancellation feature in some of its previous products. WhatsApp has this feature from last year, allowing users to withdraw messages immediately after sending them for a short time. However, it doesn't disappear, the 'deleted information' will display instead of the original text, video or image.
Instagram also has the Unsend feature, erasing it completely as if the message never existed. (Of course unless there is a notice when you send it and the recipient has read it). Users just need to touch, hold the message to delete and press 'Unsend'. Then the recipient will not receive any further notifications.
This news came only hours after news that Zuckerberg's old message had disappeared from some users' inbox. While their usage controls do not mention deleting messages and do not violate the general standard. This action is criticized, arguing that users lose faith, especially when Facebook has just undergone the Cambridge Analytica data scandal and is still in the process of investigating this case.
