The disappearing messages feature has been on WhatsApp for some time now; this is available on both iOS and Android versions. As the name suggests, the feature allows you to send messages that self-destruct after the given time. Currently, you can only set the messages to disappear after 7 days, but it seems like this will change soon as WhatsApp is working on adding more timers to the feature that will allow the messages to stick around for longer.
The New 90-Day Duration for Disappearing Messages Makes Little Sense But Could be a Worthy Addition.
WABetaInfo has spotted new evidence that suggests that WhatsApp is adding a 90-day option for disappearing messages. This was spotted in the latest WhatsApp beta update, v22.214.171.124. Once this feature rolls out, users will be given more flexibility when sending disappearing messages and can choose between options ranging from 24 hours, 7 days, or 90 days.
