This app is only good for booking flights and hotels but not good for Train reservations because once you book the train ticket through app you can not cancel or even see the train booking details in the app at all. If you want to cancel it then the only option is to login through web or call toll free. In paytm you can easily cancel or book the train tickets as compared to MMT. Please MMT update your app with the above suggestion. Please correct me if I'm wrong. Thanks. Superb!
