Planning - Calendar subscription for Gmail not working

I'm trying to add Planning calendar to my Gmail. On Planning Dashboard, under my name, is Unavailable Dates and Calendar. When I press Calendar, it opens a little drop down that allows me to choose Google Calendar or Outlook/iCal. Clicking on Google Calendar opens Google Calendar in a new window, but I can't see any added calendar and none of my Planning accepted services show up.
When I copied and pasted the Outlook/iCal calendar link into Calendar from URL in Gmail, I just three items in my calendar for each Sunday, the Call Time, the Rehearsal and the Service, regardless of whether I'm on or not.
Not sure what's going on.

Gmail will poll calendar changes every few hours, it isn't instant. After a few hours have passed, you should see your services you have accepted in your Google Calendar.
