Caldav iOS sync one-way only

I have successfully set up caldav sync with mailbox.org: when I create an event in the web client, it appears on my iPhone. However, it does not work the other way around: when I create an event in Calendar.app on iPhone, it does NOT appear in mailbox.org calendar in the web client.

How can I set up bidirectional sync?

Is it even supported?
