Google Messages for Android is adding a “Delete for everyone” option in group RCS chats, allowing users to remove sent messages for all participants. The feature is part of Universal Profile 2.7 but may not appear in all chats yet, with reports showing it only in larger groups. Older app versions may still show deleted messages. Google is also working on group chat features like invite links, QR codes and @-mentions.
