What is the default sync interval for iCal link and how to change it?

I shared my todoist feed for habit tracking (see link below). It seems to not be updated within minutes (I completed the task).



Which NC version are you using?
Which version of the calendar app?

In which interval are you calling cron?

I’ve forgotten to enable the cron. Now it works. Thanks. Still, what is the frequency? It does not seem to by synced every cron run.

Nextcloud: 20.0.2
Calendar: 2.1.3
Cron: every minute
