Read this thread and try the solution. It's been working for many others, maybe it will work for you too.

Getting A Successful iCloud Sync:

A. Restart your Modem:

Power off your modem for 30 seconds, and then power it back on. It may take up to 5 minutes for all to successfully reset.

B. New iCloud Session:

Log Out of iCloud on your Mac, and then log back in.

C. Disable/Enable Notes:

On both devices, fist enable Notes in iCloud. Once both have Notes disabled, enable notes on both.

Thanks, but rebooting did not help in my case. Also the non-sync problem only is an issue using the Notes app.

Synching of calendars, mail, etc is still working fine across my two MacBook (Pro/Air) and the iPhone.

Hello,

it looks like Apple has got their sync problem with the Notes sorted.

In the meantime the synching of Notes between my different devices is back to normal and working properly. Also the "lost" Notes on some devices are back since the sync problem got resolved.

I do find it annoying that despite this obvious outage of the sync service the status page (on the Apple website) indicated the iCloud synching as being "okay" (green dot) and working normally.

Also I am not aware of any communication by Apple explaining, or at least acknowledging, this problem. So again, as a 40+ years user of Apple products I have been completely left in the dark. Sigh. One get's used to this shrewed attitude.

Most people have already been logged out and were not able to log back in. Try a reboot. If that doesn't work, logout and reboot again. Once you're boot back up, try to log back in.

Hello, this problem is not related to Sierra or HighSierra alone. I am experiencing the same outtage of synching (of Notes) since a few days using Yosemite on an MacBook Pro and a MacBook Air.

Hello, just a short question: I am experiencing _AGAIN_ (sigh!) outtage of synching (of Notes) since a few days using Yosemite on an MacBook Pro and a MacBook Air. Do you have the same problem?
