Nextcloud 26 with NC Office old GUI, why?

I just installed Nextcloud on my Synology NAS, with a Collabora server on a VPS but I have the old NC Office interface, without the new features, why?

The command used to install Collabora on my VPS:
docker pull collabora/code
docker run -t -d -p
-e ‘aliasgroup1=nextcloud\.xxx\.fr:443’
–restart always
–cap-add MKNOD


Hi, not sure if this is what you mean, but if you are talking about the tabbed view, you can enable it by going to “View” - “Use tabbed view”.
