Mark Zuckerberg has warned Messenger users not to use the 'screenshot' option in conversations because their friends will be notified.

Facebook has announced that there will be a series of updates after activating encrypted conversations in Messenger, the same as in WhatsApp. Zuckerberg says users need to be alert to future innovations.

If a user shoots pictures of messages that disappear automatically after 24 hours, the interlocutor will be notified. So if someone sends you a message that does not want to be saved and you take a 'screenshot', they are notified immediately and vice versa.

In addition to messages, GIF images, stickers and feedback will be part of this update.
