New phone, Apple Sign On with email relay not working
I have been using the Apple sign on option whenever it is presented to me, and have been selecting to mask my email address because yay privacy.
I received my new iPhone on Friday. An app I’d previously used with my Apple sign on is now not working. I’m getting an error message because the email address associated with my Apple ID is my gmail- my account email is the relay. The relay and the account are still in my Apple profile, so Apple knows what email address it used. Why can’t I log in? Ideas of answers?
The app in question is linked to my credit file - so I don’t think it would be easy to just create a new account or I’d do that (and directly share my email address this time).
iPhone 12 Pro, iOS 14
