I have tried creating a mount point, editing the fstab file, (which then totally denied me access to the Drive 2, as in, it wasn't even listed in file explorer. I have NOT yet created a sym link...that's next.

If you just let it auto-mount from fstab, the mount is owned by root (unless specified rw access for others). If you make a mount point, for example, in your home directory and mount from commandline, then it will be owned by your user.

Many thanks to all who tried to help. I have solved my issue by using the Appimage download. That opens my files any where on my network. I have tried it with both the 0.18 Appimage and the 0.19 Appimage. The fully installed .18 still isn't accessing my files from anywhere except my home directory. I don't know why the fully installed version is showing Core 16 as my OS, it is NOT. I'm running Ubuntu 20.04 LTS. Here is what the 0.19 Appimage application shows.
