It has been a while since the rumours of the above surfaced online. Now, thanks to The Verge, we know more. Facebook Messenger 191.0 update notes supposedly mention this new function; allowing the Messenger user to delete any message she or he has sent in the last 10 minutes. Well, that is not the hour that WhatsApp gives us to do the same but it is still good. Zuckerberg will not be the only one able to delete his messages now :p.
