After updating to iOS 17, not able to sync data on iCloud (Advanced Data Protection has been set ON)

I reset my device and loaded a back up however instead of my iOS 16 back up it loaded iPad 17 and then 17.0.1 was available to update. All seems to be working now.

Yes me too!

I upgraded from IPhone XR to 15 pro and the first issue was no health data transfered!

I have now got all old data on new phone after doing an encrypted hard backup to computer but it's crazy that there is an issue with iCloud sync.

I've had regular phone calls with the same customer service representative over the past 3 weeks and each time the software engineers have simply responded asking to reset phone and do a back up!!

Their other option was to simply loose ALL ICLOUD DATA from the past 7 years and create a brand new Apple ID - loosing all subscriptions, applecare, music purchased on iTunes back in the day etc. Wtf?!!!

Crazy. I'm glad to hear that others are having issues too as it sounds like an iOS 17 specific issue.

No issues at all on iPad OS

It didn’t help me. I signed out, signed in, but I didn’t get any prompt to turn off advanced data protection. Now I am even in worse situation - all my photos gone, everything is in icloud, but I can’t connect to it.

I have the same issue. When i press resume syncing it appears to resume but will not move, and all my photos are not downloadable and neither are my icloud files.

I am on the new iPhone 15 Pro. And IOS 17.0.2

I just updated to 17.0.3 and having this exact same issue and message. clicked on it , entered the password and nothing happens. tried restarting the phone multiple times, no help. did not sign out of icloud as worried about what some users mentioning not being able to sign back in.

any ideas how to fix it? thanks.

I’m running 17.0.1 and am getting nowhere

It’s definitely not anything you did. The same message happened to me. My devices arent syncing properly, I continue getting a request to sign into iCloud on my watch and I already did., the request won’t stop. The iCloud key chain is not working. Auto delete passwords option is not working, Autofill passwords is working incorrectly so u have manually go to PW’s and copy and paste opposed to automatic. My phone wants me to use a security key in which I’ve never used before nor created before as well.

I was super excited a on the 17 update, now it’s more of a headache than anything. Sad cause everything was operating so smoothly, all 3 of my devices WERE spot on.

no. my main issue now has been that I cannot receive an invitation for airtags from my wife. We all have the same latest update of 17 and same phones. she set up the airtags and sent me an invite to track them, but I do not receive the invite. spent hours with apple support on this and no help. so I gave up for now

Since upgrading my iPhone 13 Pro to iOS 17.1.1 I get the unexpected error message on all iCloud syncing. I even upgraded my iCloud space account in case it was a memory problem. Tried resetting all settings but no improvement

my problem is as soon as i slipped up and did the update , find my doesnt work ..its like im half way signed in .. i can sign in on my pc .. when i check my storage on my pc it shows that i paid for the 2tb ( like i do every month ) yet on my phone its saying im low on storage.. nothing has backed up to my phone in 3 weeks .. also , the find my and icloud option is greyed out so thats that .. this is bull crap .. im over apple ..my phone doesnt prompt me to log in to my icloud all the time , not once since the update , but i am not connected and its a total drag

How did you get that pop up in the first place?

This still does not work for me I just updated to iOS 17.0.3 hoping they came up with a fix. My iCloud is still unusable.

did not get this message unfortunately

I just signed for the first time on a new computer, worked fine. also I'm on 17.0.3 on my iphone 11.

I’m having the same issue with iPhoto syncing from iPhone 14 pro max and iOS 17.0.3. Says it’s syncing but doesn’t.
