My Calendar power up is not working

[Noel Maher]

I am on the free version

My Gmail Cal will not display properly, some board cards appear but others do not.

I have added each board to my Google Cal, when I add a new card within a board sometimes it appears on my Google calendar but other times it will not.

This is driving me nuts!  Can anyone help?

Hi Noel! Three things that come to mind as good things to rule out: 

1. Confirm all cards that should appear on the Calendar have Due Dates assigned
2. Confirm each board's calendar URL is current. If a board's calendar URL is updated, it would break the connection to any external calendars that are monitoring it. To check, go to Google and copy/paste the URL, then cross-reference it with the URL from your boards
3. Make sure you're giving it time - Google checks your Trello boards about once per day, so it's not an immediate sync unfortunately

For point 2 - the "refresh" button next to the iCalendar Feed URL will change the URL, which would break any existing syncing for that board:
