As of April, there have been reports indicating Facebook's intention to add a messaging function to Messenger.
It has now become known that after some tests this function is available to users in some countries. Specifically, the & # 39; Submit & # 39; Of Messenger is available to users of Android and iOS users in Bolivia, Colombia, Lithuania, and Poland. At the same time, the Company undertakes to make the operation available in other markets "as soon as possible."
The "undo" function is quite simple: the user has ten minutes to change his mind and cancel his message, leaving a "note" to other users to announce the location of the deleted message. The retrieved messages will be held for a reasonable time on the company's servers in case of malicious messages initially deleted to cover the sender traces.
According to the TechCrunch site, Facebook plans to add the feature to other features, such as encrypted messages or not with "expiration date".
