4th Gen iPad and iCloud Authenication Issue.
I own a very old 4th Generation iPad (A1460).
Recently I have been receiving a notification to enter my Apple ID password in order to connect to iCloud. I enter the correct password but the authentication fails. The notification keeps coming back in an endless loop.
I did a full iTunes backup of my iPad, restored the iPad back to ios 10.3.4 and restored my backup. The same problem occurred. I again restored the iPad back to 10.3.4 this time without restoring the backup. Still the same issue. I once again restored the iPad back to ios 10.3.4 and restored my backup. Of course the same authentication issue occurred.
I tried to log into iMessage and Facetime but it also fails.
From Setting I see I am logged into "iTunes & App Store".
I see that my iPad is register with Apple at:
https://appleid.apple.com/account/manage/section/devices
However, I do not see it as part of my iCloud devices:
https://www.icloud.com/settings/
I have done a lot of online research into this issue but have not discovered a solution. I suspect that Apple has stopped older devices and older versions of ios from signing into iCloud but I have not found any evidence to support this.
Is this an isolated issue with my iPad or is it a general issue for all A1460 iPads running ios 10.3.4?
Any insight into this issue would be greatly appreciated.
I have included some screenshot here:
This is what awaits me when the iPad's lock screen is active.
If I tap "Not Now" the iPad will keep pestering me until I tap on "Settings".
After tapping on Settings I am sent to here. I enter my correct Apple ID
password (if I enter a incorrect password it lets me know with a shake
of the head) here.
And this is what I get: Verification Failed An unknown error occurred.
After tapping OK and a few seconds later the second screenshot reappears.
and the whole cycle starts over again.
P.S. Sorry I had to re-post this as there is no option to edit after Apple removed a couple of the above screenshots. Good grief!
