Couldn’t find any topic on dissappearance of notes.
It happened already 3 or 4 times that I was writing a note and it disappeared.
I had to go and look for it in the trash, notwithstanding I have the option “Confirm file deletion” turned on.
I had this happen when I first began using Obsidian where as you say notes would “magically” disappear.
There’s a post somewhere on the forum about this, that of course I can’t find, but essentially if your vault is on iCloud and you have a Windows box linked to iCloud, this can happen.
I unlinked the Windows box from iCloud and have had no problems since.
Hope that helps.
Note magically dissapeared again.
Went to the File Recovery and hopefully found a previous snapshot.
Here’s an image showing how 11:57 there was data in the snapshot and 12:02 there was zero.
Hopefully I took it from there and reconstructed.
I have, as of now, the vault in a OneDrive directory installed in my mac.
I think that OneDrive could be the culprit, but I need it because I use two computers (laptop & desktop) and need to have my notes replicated.
