@acmeCSE And yet I’ve got 5 calendars within iCloud, that I made; 3 have the busy/free field available; 2 don’t; and if I make a fresh one it doesn’t either. So it seems that at some point I somehow made iCloud-based calendars that had that field available. (1/2)
I’m now wondering: for a decade or so I used Google Calendar. I then had a period of overlap where I used Apple’s calendar app but used Google as the storage (as it were). Eventually I fully migrated. I wonder if the calendars that *do* have the field started life in Google Calendar and I somehow migrated them over intact (I’ve actually forgotten how I did that). (2/2)
@davep I think this is a similar experience others have as well. I just created a new calendar on iCloud using BusyCal. For BusyCal the busy/free flag is available and everything works fine. However, using Apple's calendar app, the flag is available…
@davep “is not”. Sorry. It seems that the flag is supported by iCloud internally, but the apps are only supporting it sometimes.
