This was said directly by Vice President of Consumer Communications Products Google Matt Klainer in the company’s official blog. He said that “given Messages’ continued momentum, we’ve decided to stop supporting Allo to focus on Messages.” Klainer said that since the beginning of this year Google has stopped investing in Allo, and bought a number of the most preferred features, such as Smart Replay, GIFs, and supports desktops for Messages.
Allo will still be usable by users until March 2019, and from then on users are advised to export all recorded conversations before this service is stopped. Google has collaborated with the mobile industry to increase the use of the Messaging application so that people around the world can more easily enjoy group chats, share high-resolution photos, receive and read messages on various Android devices. In its development, Messages has currently used 175 million people thanks to a partnership that is woven by Google with more than 40 cellular operators.
