Теги совместной работы Nextcloud в групповых папках

NextCloud 12.0.4
Автоматическая пометка файлов 1.2.2
Group Folders 1.2.0

I have a well running NC 12 installation with (more than) the above listed apps. But when I upload files to a shared folder, they do not get tagged. If I upload them to some other users folder, they do get tagged.

I tested upload via webinterface and via desktop client, both have the same result.

Are collaborative tags possible in group folders? This closed issue in the related app files_retention somehow sounds like it should work? Same issue here
