Facebook Messenger will soon allow Canadians to unsend message

Facebook

TechCrunch reports that Canadian marketing professionals can expect to have the ability to unsend message for the first 10 minutes after you hit the send button soon, and notes that a “tombstone” will be left indicating a message was retracted but Facebook will retain unsent messages for a short period of time so if they’re reported, it can review them for policy violations.

As at December 19th I have this functionality on my computer by clicking on three dots beside the message but do not see it on Android. Not sure about iPhone.
