Connect Google or Outlook (sync)
Automatic sync, with a choice of destination calendar.
As an alternative to subscribing, you can connect your Google or Outlook account in Profile → Calendar → Automatic sync. After you authorise it, events go into the calendar you choose (or a dedicated “Totil” calendar you can create).
Support note
Connecting Google may show an “unverified app” warning while it’s in testing — it’s safe to continue. Sync runs periodically, not to the second. Apple is always done via subscription (ICS).
