Ics import to nextcloud does not work

Hello everyone

I made a calendar export from my owncloud calendar (ics) an would like to import this file to next cloud.
About the function “Import calendar” I choose the ics file and changed the calendar from “Personal” to new calendar.
If I would start the import I get the Message "Import geplant " Import planed but noting happens.

What I’m doing wrong?

Thank you

Do you get any hints in your logfiles?
There are already some reports on ics problems in the bugtracker: https://github.com/nextcloud/calendar/issues?utf8=✓&q=is%3Aissue%20is%3Aopen%20ics

Hello, I don’t know why, but now it works
