2 apple ID
I received a new chip for a phone I have not used in a couple of years. Initially I used the apple ID I am using on my current work phone. But I have another Apple Id that I created a few years ago That I want to use. When I go top add it to the new phone I get a message "ID is already being used". When I look up in icloud.com it is not attached to anything. What would I be doing wrong?
