When I try to use this URL to subscribe to a calendar to my Google calendar, it does not show the events. It works for my calendar on my Mac, ok, but not Google. Any insight on this would be appreciated.

I would need an example to take a look at, but doesnt sounds like there is an issue with the feed itself, given you can use elsewhere

Hi Marc, I messaged you a calendar I have been trying with. It does sync ok with my calendar on Mac, but Google won't retrieve the events. I was able to sync a calendar from my Mac to that Google account, but not the calendar from my board—maybe a Google issue. Cheers Alex

Ive created a ticket so we can take a look at this for you

Working now, thanks

Glad to hear it :)
