 * Recent development with the plug in attempting to set up an iCal subscription–
   copy/paste the iCal link from the ‘add-on’ tab results in a pop up stating “The
   data downloaded from *** isn’t valid” in iCal. Attempted with multiple test appointment
   settings. Any thoughts?

   to validate the published link results in the following:
