End-to-end encryption has been a long-standing feature in one-on-one conversations, and extending this safeguard to group chats is a positive development. Nonetheless, there’s a compatibility limitation when it comes to cross-platform messaging between Android and iOS devices. Despite Google’s efforts, Apple has chosen to maintain its encryption approach through iMessage rather than adopting RCS. Consequently, seamless E2EE-enabled group chats can only be achieved if all members of the group are using either Android or iOS devices. Otherwise, utilizing a third-party application like Signal would be an alternative option.
