I started an appointment by mistake and it's still in progress. What do I do?

You need to delete it. To delete this appointment, go to the first step of the appointment (where the clinical history and patient information are), find the “Delete appointment” button at the top left and click on it. A confirmation window will open; click on “Yes, delete”:

Done! You’ve deleted the appointment and nothing was saved in that patient’s history. Your finances won’t be affected either.
