some iCloud data isn't syncing

Just upgraded from iPhone 14pro (ios 17) to iPhone 15 pro (ios 17.0.2) and set up the new phone via icloud backup. All data loaded in except for my messages, health data, and keychain/passwords. I get an alert in settings

`Some iCloud data isn't syncing. Your end-to-end encrypted data stored in iCloud can't be accessed on this device. It includes saved passwords and data from Health and Maps. Verify your account information to resume syncing.`


When clicking resume syncing, I enter the passcode for the phone and get a new popup to reset end-to-end encrypted data which I do not want to do so I don't lose that data. I have other trusted devices on my account that can access the data (at least the messages as far as I can see, I can't see health data on mac).


I tried wiping the phone and setting it up again from the backup, entering the 6 digit code sent to my trusted mac when logging in and I was able to get messages to load in but still none of the other data and I still get the same notification in settings. I've spoken with 5 advisors at this point who all told me my only option is to reset the data, aka delete it. Not sure if there is any other way? I have multiple trusted devices, the correct login info, and can see that the data is present in icloud, just can't be synced to the new phone.


Are there any other ways to verify the account information for icloud on the phone so that the end to end encrypted data can remain in tact and sync to this phone?

iPhone 15 Pro, iOS 17

Fixed for me. I also had this problem, with the message "Some iCloud data isn't syncing, etc.......Verify your account information to resume syncing" I clicked on the "resume syncing" link, got the spinning ball and then nothing. I noticed others on this thread had "reset" the phone with mixed results. I was trying to Verify my Account, so went to Settings, then clicked on my name, went to the bottom and clicked "sign out". The system logged me out of iCloud. I then signed back in, the error message disappeared and I now have access to all iCloud data. So glad I didn't have to spend hours on the phone with tech support.

Out of curiosity - did you do the reset from a specific device? The iPhone?


I'm nervous about which device to use (ipad, imac, iphone).


It also crossed my mind -- when I upgraded to the iPhone 15, I went from a Tmobile sim card to esim...was wondering if this could have something to do with the additional, unexpected security measure thrown at me/us by the Security Key.

Hi all

I am trying to set up a iPad mini 6 with the latest software from scratch I to am having this issue where my passwords keychain, health and map data are not syncing. I do get the resume syncing button I click it nothing happens. I enter my iPad and iPhone passcodes, and it says verification failed, I tried resetting the device to factory settings with no luck. I tried signing out of iCloud and back in with no luck.

Can anyone help me with this or does anyone have any other suggestions that I could try?

Same for me. I signed out many times from Apple Account, back on, reboot phone, nothing helps. I always get the message about some data can't be synced. If I click there, it spins, but nothing loads.


When I go to settings/icloud/advanced data protection and want to turn it on, it tells me that my Apple-ID needs to update. Then the circle spins, but nothing happens. The same happens when I try to turn on messages in the icloud settings...


I'm little bit relaxed that some other people got the same error and it's maybe related to the Apple Servers which they hopefully can fix quickly ...
