Trello Calendar & iCal not syncing

[Rae Mano]

does anyone know how I can fix this ? I have followed the instructions and the iCal link for Trello is active. But still nothing appears on my calendar

Are you able to see the cards with due dates on the Calendar in Trello directly? Is it possible that the "due dates" have been changed fairly recently? The update frequency is dependent on how often the app pings our server via the feed for updates. From experience we know, that most services or apps do this only once per day, so the changes may not have been requested by the Calendar app to be sync'ed over to the Calendar app.

You may also want to check out the Cronofy Power-Up which is a service that links calendar services like Trello and Outlook or Google Calendar, and updates much more frequently as it uses the API and is easier to set up, especially when using multiple boards: https://info.trello.com/power-ups/cronofy
