Nextcloud agenda multiple users invitation

Hello,

When creating a calendar event, I simply want copy and paste a list of Attendees separated by “space”, “comma”, “semicolon” or whatever.
But he refuses to add them all at once, I can only add them one by one.

How can I do ?

You can try by copy/paste this list:
email_01@domain.org,email_02@domain.org,email_03@domain.org,email_04@domain.org

You answered your question yourself, it doesn’t work yet. I think you should create a feature request in the Calendar repository on GitHub. Once you’ve created that feature request, please add the link to the issue ticket to this conversation.
