WhatsApp will soon block screenshots of "view once" messages - but how do you set them to disappear?

The disappearing messages feature on WhatsApp allows you to send messages that automatically disappear after a particular period of time. Here's how to use it.

How to use ‘view once’ for voice messages To send photos, voice messages, and videos that disappear after the recipient opens them once, you need to select ‘View Once’ each time.

Initially teased by WhatsApp and Facebook big wigs, the View Once feature restricts recipients from opening a message more than once.
