WhatsApp recently introduced a new feature on the latest beta version of the app called View Once mode for messages, allowing users to send photos from the app to their contacts that can only be opened once.
The feature basically ensures that any media sent by a user is only stored until it is opened, then deleted immediately. However, as users have discovered, there is a small caveat to using this new feature – WhatsApp doesn’t block users from taking a screenshot of your media, or alert you when a contact attempts to do so.
