WhatsApp is introducing new privacy features (Yui Mok/PA)

WhatsApp is to allow users to leave group chats without notifying others and control who can see when they are online as part of a privacy update to the messaging app.

As part of the update, which is rolling out this month, users will also be given the ability to block people from taking screenshots of View Once messages, which are designed to disappear after being opened.
