I have a 13 Pro and I recently updated from 16.2 to 16.3. Afterward I discovered that I was no longer signed into iCloud backup. When trying to sign in I get a message saying “unexpected error occurred, try again later.” I’ve tried restarting and trying to sign in again but I get the same error message. I’m still signed into Find my iPhone however. Any ideas?

Hello Steve M,
Thank you for using Apple Support Communities. If you’re not able to sign in to your iCloud settings, we can recommend some steps that might help out. If you're connected to a specific Wi-Fi network, try using your cellular network or a different reliable Wi-Fi network. This can help isolate connectivity issues.
You can also try refreshing your network settings. Follow this path: Tap Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before. If you're using iCloud Keychain, these settings are also removed from other signed-in devices.
Once the reset completes, test to see if this error message continues to populate. We hope these steps are helpful. Cheers.

16.3.1 fixes this. FYI.
Hello Steve M.
Thanks for that info.
Please contact Apple Support to investigate this further with you. Let them know it started after the update, you already attempted the help article, and it's occurring on both Wi-Fi and cellular connections.
Thanks.
Ive had 4 conversations with Apple obviously they are aware of issue and said they are working on it. Said to do any and all updates that i get notification for. Not updating my iPad yet. Mine is an iPone 11 pro max. Last conversation was jan 31 2023.
Hi Steve M.,
Thanks for posting in Apple Support Communities.
Two-factor authentication is the level of security on your Apple ID. It would not not prevent you from signing in to a feature like your backups. Were you able to continue the steps from the previous message?
Check whether you're able to sign in to iCloud.com using your browser.
Continue with additional steps found in If you can't connect or sign in to iCloud - Apple Support.
Regards.
I have tried connecting to the cellular network instead of WiFi and it didn’t help. This problem surfaced immediately after updating to 16.3. I would like to avoid a random shotgun approach of resetting settings.
I know other users with this problem too. Unfortunately, solutions are not forthcoming. I’m almost ready to try to see if enabling two factor authentication will help but I really don’t want to do that.
I do not. But here are some oddities. When I called in, the tier one person had the same issue and had not realized it. Next the tier two person mentioned the upgrade to 2 tier authentication as being a possible work around. Finally and the strangest is, while it shows iCloud is off, my stuff is backing up and syncing. He verified my last forced from iTunes was there.
Is this problem likely to be caused because I do not have two factor authentication enabled?
I can still sign into discussions, etc with my Apple ID. And I’m still connected to Find My…..
Apple will certainly not answer me. But thanks anyway.
I was hoping to hear from someone on this user to user support site who has actually experienced this problem. Thanks.
Yes, I am having the same issue too (“unexpected error occurred, try again later.”), update to iOS 16.3, iPhone 11, no 2FA enabled (don't wish to).
Thanks for the update. Do you have any indication that this problem has anything to do with not using two factor authentication?
That’s all very interesting
Yes it does. Thanks!
Yes it does, thank goodness!!!
