Facebook Messenger Day: Another Snapchat clone that's already downloaded on your phone

Facebook has started rolling out its latest Snapchat clone to users of its Messenger app. Messenger Day works in almost exactly the same manner as Snapchat, allowing users to post edited pictures and videos that disappear after 24 hours. It lives in the Messenger app, which features a new row of thumbnails positioned above your conversations, with each one previewing your friends' latest Messenger Day updates. You can skip through updates with taps, as you can on Snapchat, and also react to individual Day posts with private messages. Unusually, Facebook hasn't included a Like option.
