Done importing 0 contacts

I followed the steps here: https://docs.nextcloud.com/server/stable/user_manual/en/groupware/contacts.html#importing-virtual-contacts

But when I select a csv file it imports 0 contacts.

I’m unable to find out what format Contacts needs.

The docs you linked say: ‘VCF/vCard file’.

For reference: vCard - Wikipedia.

Ah right. last time I imported in Thunderbird and let it sync with Nextcloud
