WhatsApp has tested the reaction previews in your chat list
WhatsApp launched the message reactions in chats a couple of months ago. The stakeholders were late in introducing this feature with Telegram delivering the feature last December. On the other hand social media giant Instagram supported emoji reactions for much longer. But now WhatsApp developers are taking it very seriously as there is a huge expansion of emoji options for reactions. Now the Meta-owned entity is testing some of new previews for reaction of the message within the chat list.
According to WABetaInfo, the feature can not be disabled even if you turn off reaction notifications from the app’s settings. The message reaction previews are available only for handful of WhatsApp beta testers. If you are part of WhatsApp beta via Google Play beta program, you can check to see if you have got access to the new interface.
