If you aren’t quite ready to give up your plain old Instagram DM experience, you’ll be happy to hear the switchover to the new interface is optional. It’s designed to streamline the two messaging apps into one chat interface - without actually requiring users to download either app to make the experience work. The combined messaging experience is the same one Facebook began testing on a small number of devices about a month ago. That’s why we’re connecting the Messenger and Instagram experience to bring some of the best Messenger features to Instagram – so you have access to the best messaging experience, no matter which app you use. Messenger chats are now available in the Instagram app - and vice versa - according to a joint update posted by Adam Mosseri, the head of Instagram, and Stan Chudnovsky, the head of Messenger: More than a billion people already use Messenger as a place to share, hang out and express themselves with family and friends.

Facebook’s invasion of Instagram is nearing completion.
