How to start E2EE group chat
On January 27th (local time), Meta (formerly Facebook) released an update to the "Messenger" (formerly "Facebook Messenger") E2EE (end-to-end encryption) function. In addition to all users can use group chat and group calls, but also added the ability to notify each other to take screenshots and so on. Notice that the screenshot was taken (according to the picture posted by CEO Mark Zuckerberg) Meta released the E2EE function as a "secret post" on the official mobile app in 2016. At that stage, although messages and images can be sent and received, animation, sound, mapping, GIF images, responses (alright, heart shape, etc.) can be exchanged, no typing, no group chat. This update also supports video, sound, stickers, GIF pictures, response sending and receiving, and group chat. In addition, like ordinary message receiving and sending, you can display the other party's "in input" indicator. In addition, the function of displaying the transfer menu by pressing the message for a long time and displaying the notification when the other party takes a screenshot of the screen is also added. Although updates can be used in the latest version of the mobile official application, they cannot be used in the author's environment at the writing stage of this article.
