Some community members reported that Seafile can’t work with the latest CODE. After confirming with developers from Collabora, the CODE introduced a new collaboration feature that is incompatible with the current Seafile 6.0.
It will be fixed with the next release of CODE. We will also improve Seafile to work with the latest version of CODE.
CODE 2.0 was released on 2.11 (CODE 2.0)
I think the “collaborative editing” feature in combination with Collaboration links would be a very nice option.
