WhatsApp will soon have stickers for reactions. You’ll be able to use these stickers to show your reactions to specific messages. For now, the site WABetaInfo has posted four reactions: sad, love, happy and wow. It’s unknown if there will be more reactions or not.
For a change, WhatsApp hasn’t confirmed the feature, but it was seen in the latest beta version. It’s unclear when it will be released to the regular version.
A few days ago, it was confirmed that Instagram will soon have Facebook reactions. In this case, they’ll only be available in the Stories section.
All the features on Facebook seem to be gradually getting adapted by other apps, at least in some way.
