Cannot connect to Calendar and Reminders

When I click on “connect” when trying to connect Calendar or Reminders to Agenda, I got to my settings, but neither Calendar or Reminders appears as an option (see photo below). Any suggestions?

Could it be that your iPad has been configured by your work in a way that they simply don’t allow this kind of integration?

I don’t see how, it’s my first time using this app.

But is this iPad your personal iPad, or configured/managed by your work? Also, does it make a difference if you create at least once a reminder and event in the Reminders and Calendar app?

As seen on the image, he has an active VPN connection running. Maybe that prevents (internet)-access to his calendars?
