Hi Chris!
I’d be happy to help here! 🙂
Those links you are using are embed links and will not work for Event Aggregator. You will need to get the iCal address for the calendar you are trying to import.
You should go to the calendar settings in your Google Calendar and under calendar details you should see the Calendar Address. There you should be able to click the ICAL (green) button and it will show you the proper url to use as import source. Here’s what you should see in the calendar settings >Â https://cloudup.com/cSnwmSopkZX
I hope that helps! Let me know how it goes.
Best,
Victor
