Hide my email replaces your email with an apple controlled intermediate address, right? Is there any reason apple couldn't reuse the same intermediate address for you?
I thought the main things were making it so they don't have your actual email to track/trace, that when you unsubscribed they couldn't continue to spam you, and maybe let apple track spammers, all of which would be fine with a persistent fake email...
I mean, facilitating multiple accounts, while it could be nice, seems way beyond the UX apple provides and isn't a typical paradigm for most software... this seems like an apple issue.
It’s because the Sign in with Apple dialogue failed to recognize that it already has an account with said service.
