The first thing you notice is that the delete function now has a different name: if it was initially known in the menu under the name “Disappearing Messages” (later “Delete Messages”) and later as “Delete Messages”, you have First of all, we decided on the name “Expiring Messages”.
Also new: If the “Expiring Messages” are activated, the respective chats are marked in the overview with a small clock symbol next to the profile or group picture. The symbol can also be seen in the open chat window.
While the self-destruction function can be selected in individual chats for all beta users, at least only administrators can use it in groups for the time being. According to WABetaInfo, the feature is still in the test phase – a date for the roll-out for all WhatsApp users is therefore not yet in sight.
