I am trying to import events from a shared iCalendar. I created the import using the shared iCalendar URL then proceeded to preview the import. It is only showing seven events to import that are occurring in the next 30 days. However, the iCalendar has a year worth of events listed.
So, I have deleted the plugin and reinstalled it. However, it will only import 30 days of events. I set up a new import using a different shared calendar. It only imported the next 30 days of events, as well.
