If you see an iCloud maintenance message

While your account is undergoing maintenance, iCloud syncing will be paused. Syncing will resume when maintenance has been completed.

If you see a message in your iCloud settings on your iPhone, iPad, Mac or on iCloud.com that your account is undergoing standard maintenance:

• You won’t be able to sign out of or sign in to iCloud

• You won’t be able to back up content to iCloud or sync it across your devices

• You won’t be able to send or receive emails or other sharing invitations using iCloud

All Apple services connected to iCloud may be affected for the duration of the account maintenance. Syncing will begin again once maintenance has been completed.
