‘WhatsApp tests adjust notification after deleting message’
WhatsApp is testing a feature where the app will adjust the notification if the sender deletes the message. That is not possible until now. It will also be possible for everyone in a group chat to delete messages.
Deleting messages in WhatsApp has been possible for some time, but deleting messages in a group chat has so far not resulted in the message disappearing from the chat for everyone. WhatsApp is now testing a function that allows this reports WABetaInfo. In addition, the chat app comes with a function to remove deleted messages from a notification, so that users can no longer read the deleted message in the notification bar. So far it is possible.
WhatsApp prepares the servers according to the twitterer, who often has correct information about unannounced functions in the chat app. The functions can then be activated remotely, without users having to update the app. When that will happen is unknown. WhatsApp has not responded to the rumor about the new features.
