Sync vault between several AppleIDs

[Rising_Phoenix]

What I’m trying to do

Hi everybody,

I want to sync my Obsidian vault between my iPhone and my Mac. However, my iPhone is provided by my employer and uses a different AppleID, which makes things complicated.

Things I have tried

1. I have installed the newest version of Obsidian (1.5.12) on my Mac (Macbook Pro, MacOS 13.6.2) and business iPhone (iPhone XR, iOS 17.4.1).
2. I then created a new vault on my business iPhone and activated “Store in iCloud”.
3. I then shared the vault folder in iCloud with my private AppleID that is used by my Mac.
4. I can now see the folder on my mac, but it does not show any folders or files. If I create a new vault on my Mac in this folder, the vault is not visible in Obsidian on my business iPhone. So this is where I am stuck.

I found this topic in the forum, which seems to be similar:

Use Shared iCloud Folder as Vault in iOS Obsidian

Hi everybody, I have got a specific workflow-problem and hope somebody here can help me out I have started to use a shared Obsidian Vault with a Friend like this: Its based on a shared iCloud-folder from my friend which I access via Obsidian Mac Desktop App. To sync this vault with my mobile devices I connected it to a shared vault via Obsidian Sync to sync files to my phone & tablet. In general, this setup works like a charm, sync via iCloud is actually rather quick, with some…

but I was not able to understand the suggested solution properly.

I hope someone experienced from the community can help me
Regardless of that, thanks for reading and have a nice day!
