As I read http://support.apple.com/en-us/HT203511 I was a little dazed. But you gotta do what you gotta do.
My photos no longer go to My Photo Stream on my computer.
This started in October, after updating from I0S 7 to I0S 8, and now I0S 8.1.
I have HP Windows 8, updated to 8.1.
Can anyone help? After many calls, Apple has not solved my problem.
