This email address is not available. Please choose another one.
I had two apple accounts one with "xxx@gmail.com" and "yyy@gmail.com". I did not need two accounts and wanted to use my primary email (yyy@gmail.com) on the apple account I use (xxx@gmail.com).
When I tried to do so, I was greeted with the error message: "This email address is not available. Please choose another one."
Since I had no use of the secondary apple account, I deleted it (a few months ago now).
But now, even with the account that used the email deleted, I still can't use it and get the same error message. When I try to login with my primary email (the one who was linked to the deleted account), it says no appleid is linked to that email, so I guess it is deleted but then why can't I use it for my primary account and why is it not available?
