Erasing a Facebook message does not actually erase it for everyone, however Facebook is working on an Unsend function for Messenger.
At some point in our lives we've most likely all been guilty of sending a message and afterwards later reassessing our actions and also wanting we had not. WhatsApp has a fairly new function that lets you remove a sent out message prior to it reads, and Facebook is doing the same with Messenger.
Currently when you send a message via Facebook Messenger you can tap and also hold the message to access a Delete choice, as well as it will be eliminated from your discussion string (as revealed below). Other than what you can not see is that this message has only been removed for you, and your recipient can still read it. This is indicated by the term 'your copy of the message'.
Hope is coming, however. Twitter individual @wongmjane has actually spotted an in-beta Unsend function, similar to that discovered on WhatsApp. This new feature, which has actually not yet turned out to all individuals, will certainly provide you the alternative to remove for everyone.
