My partner sends me calendar invites via google calendar which arrives in my iCloud email account. I have 3 calendars sync'd w/iCloud two of which are shared with others iCloud users. On my Mac I click on the invite.ics in the email which opens the calendar and places the event on one of my shared calendars which is NOT the default calendar I have selected in calendar preferences. This is a problem because it sends notifications to the shared users. I've tried moving the default calendar to the top of the list of calendars on both iCLoud.com and my Mac calendar but it still chooses the shared calendar in the list (2nd one listed). I sent feedback to Apple a while back but no response. Is there a work-around?
