Lost notes in contacts following iOS 10 update

Following on a hint from above regarding Facebook, I solved this for me. I went in an closed syncing contacts on all my accounts aside from iCloud. This included Gmail and one or two other locations. My notes field immediately reappeared on my iPhone 6s. I imagine if I wanted the Google contacts I could re-add that account and see what happens, but I don't so I am content.

so my contact and 'my card' are two different contacts? I can see my contact t info perfectly fine - but if I select 'my card' I don't have the same information. if I enter that information it does nat save it to my card. I have checked and it appears the only place I'm syncing is to iCloud.

Apple suggests backing up your data prior to updating here > Update to iOS 10 - Official Apple Support

So hopefully you did that.

Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

Try to reset your iPhone by pressing and holding Sleep/Wake and Home buttons. If it doesn't help, try to sign out from your iCloud account and sign in back again.

Have this too, and even in an empty "Notes" field, you cannot add anything, doesn't get saved.
So i suppose a restore won't fix anything as the field seems to be bugged

It's strange, the problem occurs only with my card (Me).

If I add notes on others contacts, they are saved on all devices. If I add notes on my own card on the iPhone, they are not displayed on my iPhone 6s and my iPad Air 2 (both with iOS 10) but they are synced and displayed on my Mac. I wrote a note on my card on my iPhone and I can read it on the Mac, but not on iPhone or iPad.

I think I found the solution, while I tried to fix another thing. I needed Facebook not to access Contacts (can be set in Settings>Facebook) for another reason. But, after I retired the authorization to access Contacts, the note on Mac was immediatly synced on the iPhone and everything I added in the notes on iPhone was saved, and synced on iCloud and other devices.

So I think that, if you break the link between Facebook and Contacts, you'll access to normal use with the notes. Tell me if it's now solved for you.

To find your note in YOUR OWN contact card:

1. Go to Contacts. Select your card.

2. Scroll down to "Linked Contacts" and select your iCloud account.

Your notes should be all there! This may work for other contacts too, but I only tried it for my own contact card.

Lost mine too! This *****, had things I needed. Was able to delete all and then reset, but still lost the last 6 months! Then font is so tiny too! I held off updated till yesterday, I wish I wouldn't have!! Ugh

That was happening to me on my card. Thanks for the answer. I linked it to my iCloud account and now i see my notes again!

This happened to me as well. Did you find a resolution or a way to retrieve your notes?

Got it! Thanks, Senora FS!
