I've used it for over a year. Too much work setting up a server and trobleshooting non-stop issues. The mobile app was missing features and barely had updates. I give it a 3/5. Nextcloud seems to be captured by woke'ism too so i suspect things will get worse overtime.

Not sure how a office app can be woke but I had to wrestle with it to work correctly on a docker container with a mariadb. So much easier without running on Apache
