ubuntu 20 and 22 not mounting network shares

i have modified the fstab file to mount the share:

//**IP**/data           /home/ss/Documents      cifs    username=****,password=****,vers=3.0,_netdev,auto,noperm        0   0

at startup is not mounting the shares but after if i use:

sudo mount -a

is mounting just fine, any sugestions?
