Overview

• WABetaInfo documented the options in Android beta version 2.25.24.18 with screenshots showing new 1-hour and 12-hour durations.
• These additions would complement the existing disappearing-message timers of 24 hours, 7 days and 90 days.
• Reporting describes the 1-hour setting as suited to sensitive information, with the risk that messages may vanish before being read.
• The 12-hour option is framed as useful for short-lived coordination such as appointments or event planning.
• Coverage notes the feature remains in development, some beta users cannot use the options yet, and WhatsApp has not announced if these exact timers will ship or when.
