I would like to create a button that will allow my users to subscribe to a Calendar link. But, I want it to work for Google Calendars and also for the native Apple/iOS Calendars. Google Calendars subscription links don't seem to work reliably on iOS devices (at least in my first few tests). Google Calendar will sync to iCloud calendars, but they update REALLY slowly (every 24 hours or so). That's not terrible, but it's not great either.
Anyone have a good solution here? Maybe finding a way to sync a Google Calendar with an iCloud calendar and then offering two different links?
