Removable drive vault on another computer?

I have 2 macbooks, macbook-pro is my old intel macbook and macbook-air is my new M1 macbook.

When I connect my external hardrive vault to the macbook-pro, mylio recognizes it as a vault and starts syncing with it.

When I connect the same one to my macbook-air, it does not. The same hard drive shows up at the same path (/Volumes/2tb_seagate) on both computers.

Is there a way to make this external drive vault be recognized by mylio with both installs?

Are both computers logged into the same Mylio account?

yes they are
