According to a report by The Verge, some users at the publication started receiving a pop-up update screen on Instagram. The message read, “There's a New Way to Message on Instagram,” listing some new features. Apart from allowing users to “chat with friends who use Facebook,” the new features include a colourful overhaul of the chat screen, emoji reactions, and swiping right to reply to messages instantly.
The pop-up also said that if users do not update the app, they can still receive message requests from Facebook accounts.
By doing update, the DM icon on the home screen will be replaced by the Facebook Messenger logo. The chat screen also reportedly appear more colourful, as the sender's messaged shift from blue to purple upon scrolling. But it still not able to message Facebook users from Instagram yet.
The feature is likely rolled out in stages, as not all users can see the new feature on Instagram yet. However, the Facebook-owned app Instagram has not officially announced any details yet.
