WhatsApp is rolling out a new update that will let you use any emoji as a reaction. The company first announced the emoji reaction feature in April, but started to make it available to everyone in May.  At that time, you could only react via six available emoji: thumbs up, heart, joined hands, tears of joy, mouth open, and crying face.

Mark Zuckerberg announced the new feature on Facebook saying “We’re rolling out the ability to use any emoji as a reaction on WhatsApp.” The company is making the extended emoji reaction feature available to everyone starting today, but in case you don’t see it in your app yet, you will get it in a few days.
