WhatsApp is currently rolling out the ability to delete and revoke messages after they've been sent. The function has been in testing as a hidden feature in several earlier versions of the mobile chat app, but is officially going live this week.
Going forward, WhatsApp users will be able delete messages from conversations and group chats up to seven minutes after they've tapped the send button, as long as both sender and receiver have updated to the latest version of the app.
The new option, called "Delete for everyone" will appear in addition to "Delete for me", and is already showing up for some users when they select a message to trash.
In a published support article, WhatsApp notes that recipients "may see your messages before it's deleted or if deletion was not successful", so the feature isn't guaranteed to work all the time. It's also possible that some users may still see the messages in notifications before they're deleted.
Users aren't notified if a delete request fails, but messages that have been successfully deleted for everyone will be replaced with "This message was deleted" in recipients' chat threads.
According to WABetaInfo, WhatsApp is currently testing group voice calls internally, so it's likely this feature will also turn up in a forthcoming update.

The whole point of deleting is that the other person shouldn't know we deleted... so if it's states "message has been deleted" that's wrong... also, we should not be allowed to delete if the other person has seen the message, it'll create a lot of problems going further between the 2, because the other person will say," it's my chat records, who are you to delete the messages without my permission, even if it's your own"
Whatsapp should also notify, that delete request was failed.
I can agree with the notification issue, because that's system wide. That would be Apples job, to change the system of revoking notifications, and figuring out how the phone and the app know whether the notification has been seen or not... may be Face ID would help in that case...
