example app: airbnb when you get messages. click a message. and you'll see it will still have an indicator that you've a message, when you've none. airbnb guys are some of the best react guys out there even released open source libraries like enyzme etc. fact is no one can ever get the react thing right. don't get me started on facebook. plenty of bugs in their new app. But for some reason, instagram web is polished.
