Why does my google calander not display my tasks?
Please clarify - you've added the iCal feed to your calendar as instructed in the video next to the feed (in the Settings), it said it added it successfully and you still don't see any tasks?
Did you see a yellow "importing from URL' message at the top? If so, try to re-add it and once you see this message, close your browser, it will re-attempt to add it in the background.
Also, please note that it will always only sync the tasks that have a due date.
