Initially launched in the US, Vanish Mode later became available in several EU countries.
However, the Facebook Help Center now states that the feature is “no longer supported.” Instead, Facebook has introduced disappearing messages.
“Disappearing messages are gradually being introduced and may not be available to you yet,” the platform notes.
To access this feature, open a conversation in Messenger, tap on the person’s name, and scroll down to Privacy and Support, where you’ll find the Disappearing Messages option.

The warning message states: “If someone takes a screenshot or screen recording, a notification will appear in the chat.”
Mark Zuckerberg recently alerted Facebook Messenger users about screenshotting private conversations through a post on the platform.
In his announcement, he wrote: *“New update for end-to-end encrypted Messenger chats so you get a notification if someone screenshots a disappearing message.
“We’re also adding GIFs, stickers, and reactions to encrypted chats too.”
To illustrate the feature, the Facebook founder shared a chat between himself and his wife, Priscilla Chan. After making a corny joke about a supercomputer, Priscilla took a screenshot—prompting the notification to appear in the chat.
