I’ve been having a play with it and can’t get it to work.
Added to that calendar is this feed: https://calendar.google.com/calendar?cid=Y3ljbGV0aGVtb25rZXlAZ21haWwuY29t
The feed is working, but I can’t get it to display.
Anyone any ideas where I’m going wrong?
OK, found the problem.
In Google Calendar settings you click “make public” then below that is the “get sharable link” link. But, in true Google style, this isn’t the link to the publicly sharable calendar, from what I can make out it’s a link to share the calendar ONLY with other users of Google Calendar.
To get the proper public share link you have to scroll down a bit, to a completely random section and get the link there. Clear as mud!
I’ll leave this here in case others hit the same issue and search for the solution.
