It looks like WhatsApp released a new feature for its Android and iOS apps during the day.
This means you can quickly react to any emoji from this app. Similar apps, including WhatsApp, were limited in the emoji you might use, but that doesn’t work anymore, at least not for WhatsApp.
Since you asked…
…all emoji reactions are here! We feel ???????????????????????? regarding this.
Now rolling out to Android and iOS pic.twitter.com/Opk7x0n0VP
