Another new feature you might see in Messenger is a chat assist that'll apparently make it that much easier to send money. You can already do so thanks to a Messenger update last year, but now certain phrases will actually prompt an optional payment link in the conversation. So if you use words like "I owe you" or "pay me back," you might see a send money button pop up. You can then either choose to use it or not. This feature is still in the testing stages, but it should roll out to a few users starting today. Both the poll and the chat assist test are available only in the latest version of Messenger and only for those in the US.
