I wrote up a bunch of notes on my desktop Obsidian for a book club. I was lazy and kept the notes in my Daily Notes. When I attended the book club, I opened my iPhone app to access my vault via iCloud (which I’ve already set up), and I not only found the note had disappeared, but that I had two new daily notes! Both blank and both titled for the day.
The rest of the vault was fine. My iCloud sync is sometimes finicky so perhaps something happened as a result.
I can’t replicate or screenshot anything, but I wanted to leave a report anyways. I’ve seen some other iCloud sync problems with daily notes, but nothing like mine.
