I've just had a similar issue this evening - notes I have been making attached to a file have completely disappeared on two separate occasions, I can't find how to recover them.
Can you say more about what exactly you mean here?
Are you talking about child note items or the embedded note of attachment items?
If the former, are you saying that the text disappeared, or that the note items themselves disappeared?
Are you saying that a few words that you typed quickly without pausing disappeared when Zotero synced, or that the entire contents of the note disappeared? (All known instances of this in the past have been about the former.)
