Worst app, So many times people have complained to snapchat team but they don't update there app. I must say it does not help the user, if a user wants to change username they simply can't change it , if a user has unknowing crossed the limit of birthday they can't change it , we don't even receive a warring message. Also about new feature like music only treading music is available rest music not available. People literally need to use third party app just to get access of this simple feature.
