Hey!
In my case, it was a path like: C:\users\myuser\dropbox\obsidian\vault1.
I have re-arranged all of my content in my Obsidian configuration to be placed in one single vault. So now I hve two vaults: Master and Inbox. In Master I store everything that I want to keep, quick notes are stored in *Inbox where I decide if I want to keep them or if they can be deleted.
I follow the rules of K.I.S.S Keep It Stupid Simple.
Bythe way: I am not sure now if this thing with the direct link to the desired vaults really worked. It might be that I was sure it works but it was only a coinicidence - different vaults and different Obsidian installations (Mabook and Win10 desktop) - could be I just messed it up 
Regards,
Peter
