Hi Mez,
Thanks for getting in touch! Unfortunately, as CSV import is a standard feature of The Events Calendar, its functionality isn’t expanded upon in Event Aggregator, and scheduled import of CSV files is not supported. It’s an extra step, but perhaps you might be able to import your Google Sheets CSV files into a Google Calendar and then schedule regular imports from that calendar? If you can provide any other specifics on your situation, we can certainly do our best to offer possible solutions! 🙂
Thanks again for stopping by, and let us know if you should have any other questions!
