How to change default email associated with Apple ID to my other email address?
My default Apple ID email address will be invalid soon. I wanted to change the email address to my gmail address, which already appears as my other (2nd) backup address for my profile but this is impossible....
whenever I try to set my gmail address as the primary address, instead of the other address, I am told that this address already exists, therefor it can not be set as a “new” address.
how can I do it?
