Subscriptions are read-only, and clients decide how often to refresh.
Google refreshes on its own schedule (often 12&ndash;24 hours) and cannot be
forced. Nextcloud defaults to once a week unless
<code>calendarSubscriptionRefreshRate</code> is lowered, and refuses
subscriptions pointing at a private IP address.
