No automount after editing the fstab

/etc/fstab entry:

//192.168.80.4/video/ /mnt/video cifs x-systemd.automount,noauto,rw,iocharset=utf8,credentials=/home/osmc/.credentials,uid=osmc,gid=osmc,vers=3.0 0 0

I am searched already in the forum for my issue and found only the following thread, but this not resolved my issue:

After every reboot the mountpoint is missing.

osmc@osmc:~$ ls -la /mnt/video/Filme
ls: cannot access ‘/mnt/video/Filme’: No such file or directory

Run the command without an output or error: sudo mount /mnt/video

The access is now possible:

osmc@osmc:~$ ls -la /mnt/video/Filme

I am have the latest osmc update and the latest DSM update from my synology NAS. I am use SMB3.
