Need help opening nested folder inside Obsidian folder as a vault in iOS / iPadOS

What I’m trying to do

This is my current folder structure inside iCloud

On MacOS, I can set the directory for the vault location to be “quartz/content” to open the Obsidian folder in the correct location properly. However, I can’t select “quartz/content” folder in iOS / iPadOS, as it will only show me “quartz” folder as the only viable option

Unfortunately, I’ve got kinda locked-in into using quartz and having sync-between devices is a really important for me. Is there a way I can sort this mess out.

Some context about Quartz, it’s a pre-built react template, to easily have your obsidian notes published to the internet. Like I’ve done on my website [LINK REMOVED].

What is the ideal way to resolve this issue. Is there an alternate method to open the vault in the iOS? Should I have to do another over-haul and think about how to setup this sync again?

On iOS/iPadOS, Obsidian can only use two locations for vaults:

On My iPhone/Obsidian/ and iCloud Drive/Obsidian/

Using iCloud Drive (as you are), each folder in iCloud Drive/Obsidian/ is a vault. So,

iCloud Drive/
  Obsidian/
    VAULT1/
    VAULT2/
    VAULT3/

You could try setting up Obsidian’s iCloud Drive folder structure like:

iCloud Drive/
  Obsidian/
    content/
    docs/
    quartz/

and only ever open the content vault on iOS. The docs and quartz folder will have whatever iCloud has copied over, but they never need to be opened as vaults. I don’t know if that would work for you, but something to think about.

Here are my four vaults in iCloud Drive and what they look like in the Finder and in Obsidian mobile:

There is a hack on this thread.
