WhatsApp has recently introduced a new feature that allows you to keep your important messages even though they expire, thanks to the messages section for your lost messages at the end of the timed messages. Currently, WhatsApp is testing a feature that will allow you to activate timed messages only to the people you choose.
It is now possible to apply the timed messages feature of WhatsApp to the contacts you choose.
As you can see from the screenshot above, it’s finally possible to apply a message timer to multiple chats at once. Thus, you will now be able to use this feature only with the people you choose. It is possible to access this feature from the default message timer settings. However, WhatsApp has only offered this feature to some beta testers for now. If you are a beta user and do not have this feature yet, you may have to wait a few weeks.
