Summary of the issue you are facing:
Hi Folks,
i´ve successfully added a new Calendar within Nextcloud from a CalDav-Url.
Now, when i make changes on an event in the external calendar (e.g. change the beginning time) the change is not updated within the NC Calendar.
Any hint how to make this update appear here?
Thanks,
Dennis
