I have downloaded the Obsidian mobile app but I can’t get the sync working. I have named the vaults on both my laptop and the iPad the same and I can see the notes created on the laptop in the iPad Files app - and can edit then etc. But notes I create on the iPad don’t appear in the cloud vault.
I have seen the instructions on the Obsidian website but still can’t fathom how to do it.
I assume you mean sync with iCloud and not the Obsidian sync service.
It’s looking for a very specific folder. I found that the best way was to create a vault in the iPad app (I made one called Test, since I had no Test vault in my Mac app). It created it in a folder called Obsidian (yes, I already had a folder called Obsidian, but it wanted its own). I then used the process that Obsidian gave in their mobile help vault get everything copied over to the new location. It took a couple of restarts of the iPad to get everything to sync, but it ended up OK eventually.
You are probably already doing this but if not, you can see the precise directions here. I have sync working perfectly but it is not intuitive and obvious.
