The rumoured message reactions functionality is said to be getting additional iterations from WhatsApp. This has also been seen before, and it appears to allow users to respond to a specific message in a chat. A new reaction info page has been discovered in the works, letting users quickly check who has reacted to a message. Individual and group chat threads are both said to have message reactions available. WhatsApp’s next feature is expected to allow users to respond to messages with a variety of emoticons.
According to WABetaInfo, WhatsApp is going to add the ability to respond to messages in a future update. This feature is claimed to be in the works, and it may not be included in the most recent beta. While reactions appear underneath the message, there is a separate reaction information tab that allows users to check who has reacted to a message.
