Slightly stuggling with this, maybe it's something I am doing wrong in Google calendar.
I setup an 'issues calendar' widget on a Jira dashboard and clicked the 'Export in iCal format' link underneath it. I import the iCalendarExport.ics into Google calendar using the web interface (other->import calendar) and the issues appear in my calendar and are synced to my iphone.
I have noticed however that if I now go and add another issue to the Jira dashboard calendar this is not reflected in my google calendar. It's almost as if I've just done a one-time import rather than subscribe?
Any ideas?
