Getting "verification failed" message when setting up iPad

I spoke too soon. It has the correct email address for the account, and the user is apparently signed-in, but pressing any of "Name, Phone Numbers, Email", "Password & Security" or "Payment & Billing" produces an error message.

Logging in to iCloud causes the "Signing in to iCloud" message to appear with a spinning progress wheel that continues for several minutes before finally reporting that it couldn't log in. But afterwards the "Password & Security" item and its peers all worked correctly. And a second attempt to log in looks like it might at last have succeeded.

At this point my best guess is that Apple have delegated login handling for this generation of devices to a PowerBook 5300 running System 7, and that it can't quite keep up with demand.

I think the conclusion is: skip the initial sign in, and then just keep trying via the iCloud pane in Settings until it finally gets all the way through the sign-on process.

Thanks for your help.

That worked. And after I skipped the login process, I went to settings and found that it was already logged in to the correct Apple account. So it looks as if the "verification failed" message was just misleading.

Thanks.
