Why is it so difficult to understand what they are asking? It shouldn’t be. As of yet no one has been able to answer the question on this page.
What are you talking about. I answered Roestuff's question, even though it was complicated by oversharing (i.e., including a story about Family Sharing).
And, there is more than one question on this thread. There are several, actually.
It should be patently clear by the questions I am asking each poster, that the situations they are describing are unique, and are missing information.
Do you have a universal answer that will work for all versions of Apple/iCloud/ ID combinations? Multiple IDs? Once Apple ID, one iCloud ID? One Apple/iCloud ID, one iTunes ID? Apple ID changed before being signed out of iCloud, so issues getting previous version of Apple ID signed out?
Please share your insight with us.
And if you have a question, then write out specifically what your issue is. If you don't provide every piece of information that we are going to need to troubleshoot your particular flavor of problem, then you will also be asked questions.
The biggest issues we have with Apple/iCloud/iTunes IDs is that people have no clue how they work, where they are located, how they interact, what the difference between an Apple-domain email address is and any other email address. It's not a straightforward one answer fits all circumstances kind of thing.
So, please, just ask whatever your question is, and we will try to help.
