CardDAV don't synchronize

[rebeldu31]

Hi,

I Have a problem with the plugin CardDAV.
My addressbook is on my cloud Nextcloud.
When I added a new server on the CardDAV configuration, in the first use, I got back well all my contacts. But the new contacts added since are not visible, as non-existent. Similar for those modified or deleted.

If someone know why and how correct this.

Thank's.

PS : I'm french, sorry for my english.
