How to sync all the "flavors" of iCloud Calendar with a single Yahoo calendar?
On my iPhone (14, iOS 17.4.1), I have three color-coded "flavors" of iCloud calendar ("home", "work", and "family" - the latter shared with my wife). I also connected my Yahoo calendar, which I use when I'm on my PC (using a fourth color-code). (All have check-marks next to them when I look at the active calendars in the Calendar app.) Events added to the Yahoo calendar on my PC DO show up on my iPhone, in the appropriate color.
But I'm more likely to add new events on my iPhone. If I enter a new event on my iPhone and I specify to add it to the Yahoo calendar, it does indeed show up on the Yahoo calendar on my PC -- no surprise. But if I enter an event on ANY of the iCloud calendars, there's no syncing to Yahoo.
I could just ignore or delete the personal "home" and "work" calendars on my iPhone and use the Yahoo calendar for anything personal, but that still leaves the problem of getting things from the shared "family" iCloud calendar over to my Yahoo calendar. (It's really not helpful if my computer can't show me an event that my wife expects me to know about!)
I can't find any setting in the iPhone calendar app that would tell any of the iCloud calendars to sync with Yahoo. Do I need to "invite" my Yahoo ID to each iCloud calendar, even though the phone is already logged into Yahoo?
Thanks.
