Apple ID profile pic different among devices

No ones answer on this issue solved the problem that my Apple ID profile pic would not sync across my iPhone, iPad and Apple TV. I finally figured it out. You MUST have your name EXACTLY as the same in the Settings where your name is PLUS the name MUST be exactly the same in Contacts AND your Apple ID must only exist ONCE in your contacts for the Apple device to recognize it as your contact info. Once I did this problem went away on all devices. All my devices now have my name the same way and middle initial and problem was solved.
