Event invitations coming to wrong calendar
My default calendar is Home but all invitations come to my Work calendar (on all devices - iMac, iPhone and iPad). Every time I have to change the calendar manually when accepting the invitation. I logged into icloud.com and under Calendar / Settings / Preferences I set Home as the default under "Add event & invitations to:" but still all invitations come to Work. How can I fix this?
