The iOS immediately syncs to the cloud when something gets saved. But with the desktop app I have to wait for 30 minutes or sync manually. I think it would be good if it synced with every save or at least had the option to do so.

I have, however, found that a change will not necessarily instantly be downloaded to my other devices.
