WhatsApp introduced another awaited feature regarding messages deletion. The feature named as “Disappearing Messages”.
Once you enabled this feature on your WhatsApp, all messages sent by you will be deleted after 7 days of time. This feature does not implement for forwarded messages. This is applicable for group & individual chats but in the case of group chats, only Group Admin can enable or disable this feature.
One more noticeable thing, once the message disappears after seven days, its reply messages will still be shown there. This feature also delete your media files after seven days.
Initially WhatsApp started this feature for Indian users only. If it will be a success then WhatsApp implement this feature in Pakistan too.
