Team Folders / Group Folders not synced until manual action in client

Hi there,

I am using the groupfolders app and have created several group folders / team folders using occ.
Output from the occ cmd (sensitive information replaced by ####):

Executing: sudo -u www-data php /var/www/nextcloud/occ groupfolders:create Partners/####/Development
Group folder 'Partners/####/Development' created successfully with ID: 21

Access rights are granted successfully

Executing: sudo -u www-data php /var/www/nextcloud/occ groupfolders:group 21 "Leitung" read write share
Access rights successfully granted to group 'Leitung' for group folder 'Partners/####/Development'.

The Windows Desktop client tells me that some (group) folders could not be synced, see image below

The folders don’t seem to exceed any limits (they’re empty) and they are located on the /var/www/nextcloud

From the occ list command, everything seems to be fine, see below

The client settings are

Am I missing something here?

Best regards,

… some additional information:
nextcloud version is 31.0.5
Desktop client is 3.16.5

and I can force synchronization by manually checking the ticks in the Sync dialog.
That means, synchronization is possible in principle.
But every new folder I have to add manually.

… do I need to provide more information than the above?
I’ve seen that there’s a standard template but I don’t think it would add much.

Best regards,

Rainer
