Events aren't showing in my calendar
Commonly when Trello cards don’t sync to your calendar it is due to an issue with your Sync Rules, try checking the below.
Trello cards can’t be synced to your calendar unless you have created a Sync Rule, you can create a sync rule at https://trello.cronofy.com/. You can also see our guide on setting up a Sync Rule here.
You can double check your Sync Rule set-up at https://trello.cronofy.com/. If you aren’t sure if the Sync Rule is correct you can remove and recreate the Sync Rule on this page too.
When you created your Sync Rule did you select “Cards assigned to me”? If so, you will need to make sure you have have added yourself as a member to the Trello cards you want to sync to your calendar.
Each Trello board will need its own Sync Rule to know what to do, if you haven’t created a Sync Rule to connect your Trello board to the relevant calendar you will need to set one up.
