Messenger is used by hundreds of millions of people globally, and as of December 2023, it has adopted end-to-end encryption (E2EE) by default for chats and calls. However, when a group chat is created, it initially does not use E2EE. Interestingly, non-E2EE groups have access to certain features that are unavailable in their E2EE counterparts. One such feature, highlighted in this write-up, is the ability to send emoji reactions within group calls.
