Collabora Online Office Username instead UUID

Hello everyone,

Had connected Collabora Online successfully on my Nextcloud. My users are connected by LDAP from a Windows AD server.

But when I open and edit a Wordfile, the status bar shows the UUID instead of Username(With multiple users). How can I change it.

Are you sure you are using the latest Collabora Online connector app? This (or very similar) problem was fixed a month ago.
