My default calendar is my main/private calendar, but I want to share a second calendar and have it report proper free/busy times. When I share it and other people try to invite me, it says it can't get the free/busy times, but when I share my main calendar, it works (getting free/busy times from that calendar). I want the information to come from the other other.
How do I make free/busy checks work with the non-default calendar on Google Calendar?
