This option is presented to you only once. Once you decide to add your Lingoda class bookings to the calendar of your choice, all future class bookings will be added automatically.
Your Lingoda account will be synced with the calendar of your choice, so any class cancellations will be noted and the information will be updated in your calendar. Please note, however, that such updates may take time to be displayed, as this largely depends on the sync times of your calendar.
1) Go to the My Classes page
2) Click on Add to Calendar
3) Choose which calendar the future bookings will be added to Google Calendar or Outlook calendar
