WhatsApp makes a very strange change to disappearing messages
WhatsApp is not alone in offering a disappearing message feature. It is an idea that's fairly self-explanatory: messages can be configured to automatically delete after a certain period of time -- something that's ideal for certain sensitive information.
But in a slightly confusing move, WhatsApp is introducing the option to stop disappearing messages from disappearing. The option is called Keep In Chat, and it is being described as "your new sender superpower".
