The feature to delete a message after sending it is already enabled on Snapchat. However, it is different from the disappearing message feature of WhatsApp. When the feature is turned on, the message recipient sees it in the chat option. The message will then be deleted as soon as he turns off the chat option. On the other hand, that message stays on WhatsApp for 7 days. It is then automatically deleted.
Facebook authorities say both the recipient and the sender need to turn on the feature to take advantage of the vanish mode. Even if someone takes a screenshot while this mode is on, his notification will be available.
Recently, Facebook has started to introduce Vanish mode in Messenger in several countries including the United States. This facility will be launched on Instagram soon.
Facebook has brought new features to celebrate Virtual Diwali this year. This includes sending various avatars and personal congratulatory messages.
