I've got a Macbook pro running OSX 10.10.5, an iPhone 5s running 10.3.2 and an ipad mini 4 running 1.3.2.
Ive noticed that notes that I make on my iPhone or iPad don't seem to be syncing with the notes app on my laptop. This happened around the time I upgraded my iOS on the phone from iOS 9 to iOS 10.
I've checked and I'm still logged into my iCloud correctly on all devices.
When I go to icloud.com I can see the notes there correctly also.
Any ideas why the notes seem to have stopped syncing to my laptop and how to fix it?

Once upgraded, iOS 10.x notes won't sync with OS X 10.10 any more.
Apple has added new features to Notes in iOS 9, and again in iOS 10. Because of these new features, iOS 9 Notes cannot be synced to OS X version before 10.11 (El Capitan), and - as far as I remember - iOS 10 Notes cannot be synced to OS X before 10.12 (macOS Sierra).
Your iOS device had probably warned you before upgrading your notes, but you might have forgotten about that.
