The Download button does not work.

When the Lataa button is clicked, the browser identifies it as a calendar link and gives it to a calendar application for processing. In order for this to work, the browser must recognize the webcal:// protocol.

Most browsers work fine. However, Android devices do not support it natively. This leaves two options:

• Install the free application ICSx⁵, which will provide support for webcal:// links. For more details, see Subscribing to a calendar on Android with ICSx⁵.
• Use Google Calendar. From the menu beside the Lataa button, select Lisää Google-kalenteriin. This will add the calendar subscription to your Google Calendar accunt. From there it'll be automatically synchronized to each device using the same account. For more details, see Subscribing to a calendar on Android with Google Calendar.
