When reactions were first announced, Meta said that you’d only be able to use a select few to start out with but that support for “all emojis and skin-tones” would be added in the future.
The reactions are a useful feature, which is why other apps like Slack and Telegram have had them for a while — if you want to be able to show that a message made you laugh without clogging up the group chat, you’ve now got a way to do that. That’s going to be extra important soon, as WhatsApp is also expanding the default maximum size of group chats, with the cap going from 256 to 512 (though there have reportedly been hack-y workarounds to get past the previous limit).

WhatsApp’s blog post notes that larger groups are being “slowly” rolled out, while emoji reactions and increased file size limits are becoming available in the current version of the app. Meta spokesperson Vispi Bhopti told The Verge that the company expects reactions to be rolled out to everyone in “about a week,” but added that some users already have the feature.
