iCloud Drive Not Working iOS 16.3?
This issue has been reported by Terence:
“The iPadOS16.3 update has switched off iCloud Drive and iCloud Backup and gives a message of Unknown Error when you try to switch them back on.”
We couldn’t replicate this problem but Link has also complained about the same unexpected behavior:
“After updating to iOS 16.3, I can no longer access my iCloud drive. The iCloud drive toggle is off after the update, and a message saying “An unknown error occurred. Please try again later.” pops up each time I try to toggle it to on.”

How To Fix iCloud Drive Not Turning On
Until we have more info, please try the following troubleshooting options:
Update 1: Fix Confirmed!
0. Enable Two-Factor Authentication
Apple has introduced Security Keys for Apple in iOS 16.3, giving user another option for Two-Factor Authentication.
Apparently, iCloud now needs TFA to be enabled on your Apple ID for services like Drive, Backup and Photos to work! Thanks Rick for confirming!
So, to fix this shortcoming please proceed as follows:
- 1. Open Settings and tap on your Apple ID.
- 2. Go for Password & Security.
- 3. Tap on Two-Factor Authentication and turn it On!
- 4. Sign out of iCloud. (Settings -> Apple ID -> Sign Out)
- 5. Reboot iPhone and sign back in to your iCloud account (from Settings).
In some cases you need to sign out of iCloud, reboot device and sign back in after enabling 2FA. Thanks George for pointing it out.
1. Reboot iPhone or iPad
A fresh start can flush minor glitches and often do miracles.
Use the force restart combo: Click Volume Up, followed by Volume Down and press & hold the Side button until the Apple logo is displayed on the screen!
2. Sign Out and Back in to iCloud
If the Unknown error occurred popup continues to show up when you try to enable iCloud Drive or iCloud Backup try to sign out from your iCloud account, reboot iPhone and sign back in with your Apple ID:
- Do this is Settings -> Apple ID scroll for Sign Out.
- Force restart iPhone as described at step 1.

- 2. Scroll for Advanced Data Protection.
- 3. Turn Off Advanced Data Protection.
