Backing up outside of the Vault folder is broken

[cmyplay]

I want to store my backups in a folder that is outside of the vault root folder.

I've set the backup folder to ../_Backups/Differential

Each Differential Backup runs a notification says "Backup information looks missing".
It then creates a full new archive of my vault in the Differential folder, and the backupinfo.md is blank.

Unfortunately, this was not supported in previous versions.
However, I found it very useful, so I have implemented it as a desktop-only feature in v0.0.9. (It is pretty not a safe feature though, as it uses an internal API).
Would you mind if I ask you to check the new feature, please?

(However, an absolute path is recommended).

I am so sorry I did not notice that it hadn't been fixed for a year (or, broken possibly again?).
Relative access has been properly supported in 0.0.18.
I would appreciate it if you could confirm this!

Note: since you may not be able to see it anymore, I will close it in a while.
