Changing primary email of my Apple ID, but the old one still appears
I’ve changed the email address of my Apple ID and deleted the old one.
Though I was able to change the email for each service by logging out and logging in again with the new email, when I go to Settings my old email address still appears at the top.
Moreover, if I select “Sign in with Apple” on some Apps, the old email address appears.
If I log out in order to log in with the new email, the device says all the data will be erased from the device.
But the account is the same: how can I change email address without deleting everything?
I know all the data stays on iCloud, but I prefer not to download all again, as I have large files stored on my device from iCloud.
Thank you!
