The difference between NO WhatsApp old version and NO WhatsApp updated version lies in the features offered. In the old version, fewer features were available as compared to the updated version. Now you can get many exclusive features such as DND mode, app lock, customization, data backup, hiding last seen and blue ticks, light and dark mode, unlimited themes, unique font styles, hide status view, lock chat option, hiding typing, anti-revoke messages, status download, and showing blue ticks after reply.
