Meta boss and Facebook founder Mark Zuckerberg has warned Messenger users against taking screenshots of chats - as soon friends will know when you've done so.
A new series of updates to Facebook Messenger have been announced, including end-to-end encryption like on Whatsapp, and Zuckerberg has warned people to be wary of one of the new features.
He said that users will be notified if someone screenshots a disappearing message, as the texts are supposed to automatically vanish after a set period of time, as the Daily Star reports.
