Google has now announced that it will stop supporting Allo altogether. Instead, Google will shift its focus to Android Messages, and bringing new features to the app, to make the SMS experience more efficient. The company says that it will keep Allo working till March 2019, after which it will no longer be available.
“Given Messages’ continued momentum, we’ve decided to stop supporting Allo to focus on Messages. Allo will continue to work through March 2019 and until then, you’ll be able to export all of your existing conversation history from the app,” the company added.
To download all the chat history, open the Allo app, head to Settings > Chat and then select either Export messages from chats or Export stored media from chats.
