How to add another email address to my Apple ID?
Hello,
Two email addresses and two phone numbers are connected to my Apple ID.
I'd like to add a third email address. But when I try to do so in my Apple ID account settings, I get this message:
"This email address is not available. Choose a different address."
Why would an address be unavailable? I set up this address; it's mine. It's a gmail address.
I've checked whether I might have created a second Apple ID using this third address. I don't think I did, and I find nothing to suggest that I have a second Apple ID.
Any advice?
Thank you.
