I've been running a 2014 MBP 13" on Yosemite for a few months and the notes app would never fully sync to my iPhone or iPad. Sometimes it would sync the first sentence, sometimes the whole thing, and sometimes nothing. It's not a settings issue. It does sync everything perfectly about 1 in 5 times. Things I've tried: 1) I only have 1 iCloud account. This is is not about syncing the wrong accounts. 2) I've turned off iCloud and turned it on on all 3 devices. Mixed results. Sometimes it sees the new notes, sometimes it doesn't. It's totally random. 3) I reformatted my Mac. Same issue. My solution: Having to sit there and make sure that little sentence updated properly is ridiculous. I just moved to a 3rd party app that syncs instantly with a similar ease of use. This and Apple maps I've completely given up on. Am I the only one?
