Sometimes don’t you wish you can undo certain things or unsend certain messages? Well, Snapchat users now have that option. You can delete messages you’ve sent on the service (including group chats) after you’ve sent them. You just need to hold down on the message and you’ll get the option to delete it from there. Like taking screenshots on the service, those you are talking to will know you deleted a message but if they haven’t seen it yet, then they don’t have to know what you just sent, saving you the embarrassment of having to explain yourself.
