Earlier this year, Facebook talked about how it secretly deleted some old messages sent on Messenger by its CEO and founder Mark Zuckerberg. It wasn’t a feature that was available to normal Facebook users, though. When we deleted messages on the Messenger app, it gets deleted from our end but stays in the recipient’s inbox. Around April, Facebook said it was working on implementing this feature for all users but didn’t give a timeframe for its implementation. Now, it looks like the company is testing it out. Tech tipster Jane Manchun Wong tweeted screencaps of the unsend feature appearing on an Android device.
A prompt to “Unsend Message” shows up above the “Delete Message” option when you try to edit a message sent in a conversation. If you choose to unsend the message, a pop-up will appear to confirm the choice. It says “Your message will be removed from the chat, and you.” According to Wong, there will be a time limit for when you can unsend a message, similar to the 30-second window you get for Gmail. She didn’t specify though how long Messenger’s unsend time limit is.
