Problem with fstab after 23.04 upgrade - mounts now read only

I ran an older Ubuntu version that approached EOL, so I upgraded to 23.04 yesterday.After the upgrade, none of my network mounts worked any more.

Here's the old line from fstab:

//192.168.1.2/FolderA  /home/username/Desktop/FolderA cifs defaults,username=USER,password=123,vers=1.0

Now when I change the vers=1.0 to 2.0, the directory mounts fine, but read-only.

What am I not seeing here?
