Sync iCloud calendar with Cozi
I have just started using Cozi Family Organiser as a shared calendar with my partner. However for the set up, Cozi is asking for an iCloud Calendar URL but I'm not sure where I get this from. Anything I try comes up with an error message basically saying the URL should end in .ics. I am not very 'up' with this sort of thing so any help in plain speak would be gratefully received!
