Notes are not syncing

I've also been having this issue, for a few weeks now.

I had tried all the suggested solutions, but none worked.

Here's what just worked for me, instantaneously:

1. Go to Settings on your iPhone.
2. choose Notes
3. choose Accounts
4. choose Fetch New Data
5. choose iCloud
6. on this page, (1) ensure "Push" is checked under SELECT SCHEDULE, and (2) ensure "Notes" is checked under PUSHED MAILBOXES. (on my iPhone, Notes under Pushed Mailboxes was not checked)
7. then, hit the Back arrow at top left to return to Fetch New Data, and under FETCH, ensure "Automatically" is checked
8. Exit out of the iPhone settings
9. at this point, my MacBook Notes immediately synced with my iPhone Notes.
10. to confirm, I did a test note on my MacBook and within seconds the test note appeared on my iPhone Notes.
11. and to further confirm, I did a test note on my iPhone and within seconds that test note appeared on my MacBook Notes.

Hope this works for you!

Same issue here.. About a week ago syncing stopped working between my iPad, iPhone, and iMac.. None of the 'fixes', including the one posted here have helped.. Occasionally one device will update, and I'll see a new note from that device on the web-notes app, but on none of the other devices..

Its broken..
