I just got a new device and all notes were synched from iCloud with no complaints. However, I have noticed that the order my notebooks synced was not what I expected. I am not sure in what order you currently sync the data but I would love it to be based on the notebooks that were last edited. For example, if i get a new device and want to use it right away for taking notes in class, I want my most recent notebooks to sync first so I can use them
