A new feature allowing WhatsApp users to mark messages as spoilers is currently under development, as revealed by WABetaInfo. This capability will enable messages to be obscured with a gray bar, requiring recipients to tap to view the hidden content.
The spoiler formatting will be accessible alongside existing options such as Bold and Italic. Users can apply this feature by selecting the option or by typing ||double pipes|| around the text they wish to conceal. While this feature is being tested in the latest TestFlight build, details regarding its compatibility with images or other message types remain unclear.
Although the release date is not specified, the ongoing testing on WhatsApp’s Android beta suggests that users may see this feature implemented relatively soon.
