The dislike button something a lot of Facebook users have been asking for but it isn’t coming to the main app, instead it shows up on Messenger. The social media giant is testing out reactions with a small group of users. And aside from including the usual reactions you can do for Facebook posts, there’s also the thumbs up and thumbs down (a.k.a. dislike) options. However, Facebook says this is more of a “no” button than dislike.
Reactions option can be activated when you hover over messages sent in a thread. You can tap the emoji button and select the reaction you want to make. This shows what statement you are reacting, too, which will come in handy if you’re in a group thread and delayed responses cause confusion about the conversation. It is similar to Slack’s Emoji Reactions and the recently-added Tapback emoji on iMessage.
