To start, postpone or cancel a scheduled training, first go to the training overview. Select the day of the respective training in the calendar and press on the scheduled training now located there. A window will open where you can choose between "Start training", "Postpone training" or "Cancel training". If you now press "Start training" or "Cancel training", the training will be started or cancelled directly. If you decide to postpone the training, you will get to the already familiar overview where you can select a new time.
