WhatsApp is rolling out a new feature where users’ profile pictures appear in notifications. The feature is rolling out for iOS devices for now and is part of the 18.104.22.168 beta version of the app. However, only limited users can see profile pictures in notifications, as WhatsApp is still testing the feature.
When you receive a notification from a single contact or group chat, the profile picture of the sender will appear in the notification.
The feature is not enabled for all accounts, which WhatsApp plans to do later.
