Q: "I have sync issues with iCloud: I have multiple calendars on my Mac. This is where I keep track of all my dates. I have activated all the proper settings for syncing across from iMac to iPhone. When I go to the Mac version and display the calendars. I see three groupings, which all I have ticked in the left panel. When I see the calendar on my iPhone, only that one calendar which shows up in the first two groups. What happened to the rest calendars? Why my Mac calendar not syncing with iPhone and I can't see them on my iPhone? Any suggestion?"
