I have been using Duolingo for a year. During that time I have been able to practice my language skills in return for gaining 'hearts' (one loses a heart every time one makes a mistake).In the middle of November Duolingo changed the rules and I no longer get the option to do practice lessons in order to regain hearts. Instead they want me to purchase them or 'add friends'. This is not something I am comfortable with, I only add people I know as friends.Despite leaving numerous feedback messages (which are ignored) nothing has changed.Please Duolingo, stop ruining the customer experience and give us back the opportunity to practice to earn hearts. It helps to improve our language skills which is surely what your app is based on?
