As has been documented elsewhere google takes 8 - 24 hours to update calendar subscription feeds. This is a real pain for us because while we love the Airtable calendar view we need to be able to see it with our other google calenders, and it is absolutely essential that it be updated in real time.
I’ve played around with using Zapier, which is great when I add a new record. That said, it doesn’t offer a record change in Airtable as a trigger to update the calendar, which is very limiting.
Has anyone found a successful workaround?
