iPad Air iCloud Data Isn't Syncing

[Felipermejia]

Hi! I'm new to this forum.

I have a question. I just got a new iPad and is allready seted up. I used my old iCloud account, and I can use it normally. However, from time to time, a message pops up saying that "Some iCloud Data Isn't Syncing". Then, when I try to complete the syncing process, it asks for the iPhone Passcode I had like 6 or 7 years ago that I can't remember, and I don't have it anymore.

Any ideas? Is this already a thread for this?

Thanks!

I have seen this a few times before where certain apps were installed from a different Apple ID.

Might be worth you checking to see if any of your apps have not been downloaded onto your new iPad?

The error message for apps is different.

For the issue the OP is describing, I think this happens when end-to-end encryption gets messed up.

I see it quite a bit since I have like 20 devices on my Apple account (a bunch of old iPhones and iPads). In particular, the error shows up frequently for me when I have iOS 14 devices actively using the account. I know the passcode so I just enter it to fix the error. The iOS 14 devices are usually kept powered off and are only powered on when I need to use old apps to minimize getting that error.

Try going to your device list and remove your old iPhone.
