I have detected that this issue also happens when I use the "new note" button from with the desktop app in Mac
Last time was a few minutes ago, at 10:29 (CEST) I captured the note and didn't appear as shared until I quit the application and start it again at 10:33. After that, the clipped note and the "new note" both appeared as shared
