WhatsApp is testing a redesigned Disappearing Messages section which is easier for users to navigate. It is just available to some Beta users, so if you can’t see it yet, you should wait for an update
WhatsApp is planning to revamp its Disappearing Messages section, making it easier for users to navigate.
The feature allows you to set a time frame for texts to automatically disappear so that conversations you want to delete will disappear.
The changes for the section are now rolling out for some WhatsApp beta Android 2.22.24.9 versions, according to WABetaInfo.
A blog post on the website explains the redesigned section has not been released to all beta testers so if it is not available for your account yet, you should wait for a future update.
