Using rclone to sync with Dropbox

I've setup a comtainer with this file

services:
  rclone:
    image: rclone/rclone
    container_name: rclone
    environment:
      - TZ=Europe/Zurich
      - PUID=1001
      - PGID=100
    volumes:
      - ./config:/config/rclone
      - /pool0/rclone/dropbox:/data
    command: >
      mount Dropbox:/ /data
      --allow-other
      --allow-non-empty
      --vfs-cache-mode full
      --dir-cache-time 72h
      --poll-interval 15s
      --verbose
      --uid 1001
      --gid 100
    cap_add:
      - SYS_ADMIN
    devices:
      - /dev/fuse
    security_opt:
      - apparmor:unconfined
    privileged: true

and created the apprpriate rclone.conf file with the token for my Dropbox account. I get no errors and even got rclone to see the server:

docker exec -it rclone rclone about Dropbox: --config /config/rclone/rclone.conf

got me

But unfortunately no files are synced but likewise no errors are logged:

Has someone else more luck?
